Abstract:
Stimulus-active polymers can change their shapes with respect to configuration or dimension upon exposure to a particular stimulus such as heat, electricity, light, magnetic, solvent and pH value. These unique characteristics enable stimulus-active polymers to be used in a myriad of fields, including clothing manufacturing, automobile engineering, medical treatment, and aerospace engineering. Stimulus-active polymers can be applied in smart textiles and apparels, intelligent medical instruments and auxiliaries, artificial muscles, biomimetic devices, heat shrinkable materials for electronics packaging, micro-electro-mechanical systems, self-deployable sun sails in spacecrafts, miniature manipulator, actuators and sensors, and many more. This paper presents some recent progress of soft smart materials and their applications. Special emphasis is focused upon shape memory polymer (SMP), electro-active polymer (EAP) for aerospace engineering such as space deployable structures and morphing aircraft, which has highlighted the need for development of these materials. A detailed overview of development in these smart soft materials, of which the undergoing and future applications are used in adaptive structures and active control, is presented. The paper concludes with a short discussion for multi-functional soft smart materials and their composites that are expected to extend the range of development and applications available to the related researches and engineers.

Abstract:
The effect of various radiations to a polymer is more complex and intense, compared to that in other materials, in view of the more complex structure and low bonding energies (5 10 eV for covalent bonds of the main carbon chain). Since the energy delivered to the polymer in most irradiations (including even beta and gamma rays of 1 to 10 MeV) exceeds this energy by many orders of magnitude, there is a high risk of radiation damage to all kind of polymers. However, engineering polymers (PC, PMMA, PVC, etc. and newer ones) as well as electro-active and other functional polymers (conducting polymers, polymer electrolytes) are finding ever increasing applications, often as nanocomposites, e.g. chemical and biomedical applications, sensors, actuators, artificial muscles, EMI shielding, antistatic and anticorrosion coatings, solar cells, light emitters, batteries and supercapacitors. Critical applications in spacecrafts, particle accelerators, nuclear plants etc. often involve unavoidable radiation environments. Hence, we need to review radiation damage in polymers and encourage use of newer tools like positron annihilation spectroscopy, micro-Raman spectroscopy and differential scanning calorimetry (DSC). Present review focuses on irradiation effects due to low energy ions (LEIs) and swift heavy ions (SHIs) on electro-active and engineering polymers, since gamma-and electron-beam-irradiations have been more widely studied and reviewed. Radiation damage mechanisms are also of great theoretical interest. Contents

Abstract:
Owing to the increasing number of industrial applications of electro-active polymers (EAPs), there is a growing need for electromechanical models which accurately capture their behaviour. To this end, we compare the predicted behaviour of EAPs undergoing homogeneous deformations according to three electromechanical models. The first model is a phenomenological continuum-based model composed of the mechanical Gent model and a linear relationship between the electric field and the polarization. The electrical and the mechanical responses according to the second model are based on the physical structure of the polymer chain network. The third model incorporates a neo-Hookean mechanical response and a physically motivated microstructurally based long-chains model for the electrical behaviour. In the microstructural-motivated models, the integration from the microscopic to the macroscopic levels is accomplished by the micro-sphere technique. Four types of homogeneous boundary conditions are considered and the behaviours determined according to the three models are compared. For the microstructurally motivated models, these analyses are performed and compared with the widely used phenomenological model for the first time. Some of the aspects revealed in this investigation, such as the dependence of the intensity of the polarization field on the deformation, highlight the need for an in-depth investigation of the relationships between the structure and the behaviours of the EAPs at the microscopic level and their overall macroscopic response.

Abstract:
The present PhD thesis deals with the synthesis and characterization of functionalized ferrocenes with up to four aldehyde and vinyl groups and their usage as monomers to produce novel ferrocene-based oligomers with conjugated backbones via ADMET (acyclic diene metathesis) and HWE (Horner-Wadsworth-Emmons) reaction protocols. In addition, ferrocene-containing polymers (linear, cross-linked and co-polymers) with aliphatic backbones generated by anionic bulk and solution polymerization routes, and their electrochemistry behaviors were studied. The main aspects of this work lies in the enhancement of the electrical properties of the ferrocene-based materials (oligomers or polymers) by varying the polymer backbone, providing multi-functionalities for cross-linking and co-polymerization processes and thereby increasing the molecular weight of the products, furthermore, the application as electro-active materials, especially for the charge storage purposes is discussed. High monomer consumption, relatively high molar mass as well as longer chains were achieved by bulk protocol. Electrochemical measurements (CV) reveals that formyl-ferrocenes bearing more than two formyl functionalities are very electron poor materials and easily decomposes upon oxidation. Reducing the measurement temperature and the usage of [NnBu4][B(C6F5)4] as electrolyte allowed for reliable behavior. A linear correlation between the redox potential and the number of the formyl functionalities was found. Multicyclic measurements showed that ferrocenyl / ferrocenium redox couples in the polymeric materials are stable at least up to 100 cycles. The spectro-electrochemical studies show that the conjugated materials (oligomers) have electron transfer interactions (IVCT) through the chains, while the aliphatic backbone between the ferrocenyl units (poly vinylferrocene materials) hindered the metal-metal coupling along the chain and only a ligand-to-metal charge transfer excitation could be observed
Die vorliegende Doktorarbeit beschäftigt sich mit Synthese und Charakterisierung von funktionalisierten Ferrocenen mit bis zu vier Aldehyd- und Vinylgruppen und ihrer Verwendung als Monomere für neuartige ferrocenbasierte Oligomere mit konjugiertem Rückgrat unter ADMET (acyclic diene metathesis) und HWE- (Horner-Wadsworth-Emmons) Reaktionsbedingungen. Zusätzlich wurden ferrocenhaltige Polymere mit einem aliphatischen Rückgrat durch Polymerisation mit und ohne Lösemittel hergestellt und ihr elektrochemisches Verhalten untersucht. Das Hauptaugenmerk dieser Arbeit liegt in der Optimierung der elektrochemischen Eigenschaften der ferrocenbasierten Materialien (Oligomere oder Polymere) durch Variation des Polymerrückgrats, welche zahlreiche funktionelle Gruppen für die vernetzte Polymerisation und die Co-Polymerisation liefert. Durch diesen Prozess wird das molekulare Gewicht erhöht. Zusätzlich wird die Verwendung als elektroaktive Materialien insbesondere für die Energiespeichertechnik diskutiert. Durch lösungsmittelfreie Reaktionsbedingungen wurden ein hoher Monomerumsatz, relativ hohe molare Massen und zugleich längere Polymerketten erzielt. Elektrochemische Messungen (CV) zeigten, dass Ferrocenmoleküle mit mehr als zwei Formylgruppen die Elektronendichte an der Ferrocenyleinheit verringern und bei Oxidation leicht zersetzt werden. Erniedrigung der Messtemperatur und die Verwendung des nur schwach koordinierenden Leitsalzes [NnBu4][B(C6F5)4] führten zu aussagekräftigen Ergebnissen. Weiterhin konnte ein linearer Zusammenhang zwischen dem Redoxpotential und der Anzahl der Formyleinheiten aufgezeigt werden. Mutlizyklische Messungen bestätigten, dass das Ferrocen / Ferrocenium-Redoxpaar mindestens 100 Zyklen stabil ist. Mittels spektroelectrochemisches Messungen konnte gezeigt werden, dass konjungierte (oligomere) Verbindungen eine elektronische Wechselwirkung (IVCT) aufweisen, während aliphatische Rückgrade eine Wechselwirkung zwischen Ferrocen / Ferrocenium (polyvinylferrocenbasierte Materialien) verhindern und nur ein LMCT Übergang (Ligand zu Metall Charge-Transfer) beobachtet werden kann

Abstract:
Dielectric elastomers are electroactive polymers, which change size and shape in response to an electrical field. Dielectric elastomer actuators (DEAs) are highly promising new technologies in optical applications such as tuneable optical lenses, diffraction gratings and active camouflage. This thesis aims to develop a new approach to create a strain actuated compliant colour changing device that is controlled using DEAs as they offer stretchability, low weight, high efficiency, low cost and the possibility for miniaturisation. Conventional DEAs use transparent elastomeric materials with no significant colour change with strain. Conversely, liquid crystal materials are known to display dynamic colour changing behaviour, thereby making them good candidate materials. The thesis examines both the potential for colour changing soft actuators and the upcoming challenges in this field as well as the key concepts around liquid crystals that exhibit colour change. An initial approach was aimed at creating colour changes using dielectric elastomer actuators that drove a masked positioner. This method showed colour change since the mask changes the colour visualisation. The second approach used polymer dispersed liquid crystals, such as a nematic liquid crystal within a reactive silicone resin. The immiscibility of these compounds resulted in a dispersion of the liquid crystal droplets in the silicone matrix. However, the optical properties could not be controlled through mechanical deformation alone and the alignment of resulting LC droplets in the PDLC films was sensitive to the substrate used to perform the actuation. The next approach used reactive cholesteric liquid crystals (CLC) instead. A thin film coating process was preferred to carefully control the film's thickness by stretching. In free standing films a planar cholesteric alignment was obtained with mesogens aligned parallel to the substrate and colour was achieved based on the selective reflection of light. A transfer print technique was introduced to combine CLC coatings with elastomeric substrates that can be stretched. However, no colour change was achieved in response to mechanical deformation primarily due to the modulus and strength mismatch between the thin film and the elastomeric susbstrate material. Finally, lightly crosslinked liquid crystal elastomers using a combination of reactive and non-reactive liquid crystals were produced that were compatible with elastomer substrate materials. In free standing films planar cholesteric alignment was obtained with mesogens aligned parallel to the substrate. Successfully a reversible colour change based on selective reflection of light was achieved in response to a mechanical deformation.

Abstract:
L’utilisation de systèmes robotiques pour la navigation dans des zones confinées pose des défis intéressants sur les thèmes de conception, de modélisation et de commande, particulièrement complexes pour les applications médicales. Dans ce contexte, nous introduisons un nouveau concept de robots continus, fortement prometteurs pour des applications biomédicales, dont la forme complexe, la dextérité et la capacité de miniaturisation constituent des avantages majeurs pour la navigation intra corporelle. Parmi cette classe, les robots à tubes concentriques (RTC), qui constituent notre point de départ, sont améliorés grâce à un actionnement embarqué innovant. Nos travaux s’articulent autour de deux thématiques aux frontières de l’état de l’art. D’une part, nous avons proposé une modélisation générique et conduit une analyse cinématique approfondie de robots continus basés sur l’architecture des RTC standards et ceux avec changement de courbure de leurs tubes dans deux variantes : courbures unidirectionnelle et bidirectionnelle. D’autre part, leur commande cartésienne en pose complète est introduite avec une validation expérimentale sur un prototype développé de RTC standard, ainsi que les simulations numériques d’une loi de commande comprenant la gestion de la redondance des RTC à changement de courbure. D’autre part, nous avons effectué la synthèse, la caractérisation et la mise en œuvre de micro-actionneurs souples basés sur les polymères électro-actifs (PEA), intégrés pour la première fois dans un robot continu.Ainsi, l’asservissement visuel d’un prototype de robot télescopique souple est proposé avec des précisions atteignant 0.21 mm sur différentes trajectoires
Major challenges need to be risen in order to perform navigation in confined spaces with robotic systems in terms of design, modeling, and control, particularly for biomedical applications. Indeed,the complex shape, dexterity, and miniaturization ability of continuum robots can help solving intracorporeal navigation problems. Within this class, we introduce a novel concept in order to augment the concentric tube robots (CTR) with embedded actuation. Our works hinge on two majorcutting-edge thematics. On the one hand, we address modeling and kinematics analysis of standard CTR as well as variable curvature CTR with their two varieties : single and double bending directions.Furthermore, we perform the experimental validation of Cartesian control of a CTR prototype, anda task hierarchy based control law for redundancy resolution of CTR with variable curvatures. Onthe other hand, we develop the synthesis, the characterization, and the integration of soft microactuatorsbased on electro-active polymers (EAP) for the first time in a continuum robot. Thus, thevisual servoing of a telescopic soft robot is performed with precisions down to 0.21 mm following different trajectories

Ce travail de thèse porte sur l’étude de deux éléments au cœur d’un système de nanopositionnement et de micromanipulation : a) un capteur interférométrique intégré sur puce ; ses caractéristiques, particularités et potentiels sont étudiés en détails ; b) un élément utilisable en capteur et actionneur : un polymère électro-actif à flexions.L'interféromètre PicoMove est le résultat de l'étroite collaboration entre LISV et l’entreprise TeemPhotonics. Cet interféromètre, qui fonctionne dans le domaine de l'infrarouge moyen (1,55 µm) est basé sur la technologie des guides d'ondes optique lui offrant une plus grande robustesse vis-à-vis de l'environnement extérieur. son architecture est basée sur une structure Michelson-Young modifiée. Des expérimentations ont été mises en œuvre pour caractériser ses performances. Il a été démontré une résolution sub-nanométrique et un très faible niveau de bruit. Une densité spectrale de puissance de 100 fm/√Hz a été atteinte en condition statique.En outre, sa robustesse aux conditions environnementales est démontrée, et ses sources d’erreurs et spécificités métrologiques sont discutées au travers d’une application sur un étage de nanopositionnement, fonctionnant avec un moteur à bobine mobile et un guidage flexible.Le second point de cette thèse concerne l’étude des propriétés électro-mécaniques d'un polymère électro-actif ionique (IEAP) en configuration poutre encastrée. Il est capable de fonctionner en mode actionneur et en mode capteur. Pour la partie actionneur, sa raideur et fréquence propre sont déterminées.

It has been demonstrated nanometric resolution and very low noise level. A spectral power density of 100 fm/√Hz was reached under static conditions.In addition, its robustness to the environmental conditions is demonstrated, and the metrological specificities are discussed with details about the specific error sources. It is applied to a nanopositioning stage using mobile coil and flexible guidance.The second point of this PhD work concerns the study of electromechanical properties of an ionic electroactive polymer (IEAP) in a flexible cantilever configuration.

Abstract:
The control of boundary layers either for skin-friction reduction or for fight control can be achieved by their manipulation using deformable surfaces. In the case of the former, it is known that the manipulation of coherent structures in the turbulent boundary layer can lead to significant drag reductions. However, the challenge is to find actuators and sensors that are functional at these spatial scales (10 micron to 0.1 mm) and the associated temporal scale (100 kHz). Electro-Active Polymers (EAPs) provide excellent performance, are light weight, flexible, and low cost. Therefore EAPs, and in particular Dielectric Elastomer Actuators (DEAs), provide many potential applications as micro-actuators and micro-sensors. Modelling DEA devices is a cost-effective way of providing a better understanding of the devices and optimising their designs. Acquiring a model for the EAP material itself is the first essential step in DEA modelling. A modelling technique taking into account the material non-linearities and its behaviour at large deformations (`hyperelasticity') is presented in the third chapter of this thesis. The main challenge in modelling DEA devices is the modelling of their electro-mechanical coupling. Commercially available electro-mechanical modelling does not apply to non-linear materials such as EAPs. The ANSYS Finite Element (FE) software is the tool used in this work to develop a novel model presented in the fourth chapter. Various means of optimising the design of DEA devices are suggested in the sixth chapter using the developed DEA model. A novel design of an EAP-based pressure sensor is suggested in the seventh chapter; FE modelling is used to study the abilities and performance of such a device. To complete the model, its time-dependent properties are examined by a modal analysis examined in an eighth chapter. The thesis is completed by examining the potential for DEA in providing a `smart' surface for distributed aerodynamic control.

The design and fabrication of electro-active polymers (EAP) actuators, in the form of active dimples is described. Active dimples alter the flow by creating time-dependent vorticity flux at the wall, by virtue of changes in surface pressure gradients and local surface accelerations. Potential elastomer films for the EAP dielectric are evaluated. It was found that elastomers could not be characterised using uniaxial testing. Instead biaxial testing, in the form of bulge tests, was carried out. Electro-mechanical tests are used to evaluate the dielectric breakdown strength and strain at different electric fields.

Abstract:
Mechanical devices that include home appliances, automobiles, and airplanes are typically driven by electric motors or combustion engines through gearboxes and other linkages. Airplane wings, for example, have hinged control surfaces such as ailerons. Now imagine a wing that has no hinged control surfaces or linkages but that instead bends or warps to assume an appropriate shape, like the wing of a bird. Such a device could be enabled using an electro-active polymer technology based on electronic artificial muscles. Artificial muscles act directly on a structure, like our leg muscles that are attached by tendon to our bones and that through phased contraction enable us to walk. Sensory feedback from our muscles enables proprioceptive control. So, for artificial muscles to be used appropriately we need to pay attention not only to mechanisms for muscle actuation but also to how we can incorporate self-sensing feedback for the control of position.

Abstract:
Carbon nanomaterials (CNMs), especially carbon nanotubes and graphene, have been attracting tremendous attention in environmental analysis for rapid and cost effective detection of various analytes by electrochemical sensing. CNMs can increase the electrode effective area, enhance the electron transfer rate between the electrode and analytes, and/or act as catalysts to increase the efficiency of electrochemical reaction, detection, adsorption and removal are of great significance. Various carbon nanomaterials including carbon nanotubes, graphene, mesoporous carbon, carbon dots exhibited high adsorption and detection capacity. Carbon and its derivatives possess excellent electro catalytic properties for the modified sensors, electrochemical methods usually based on anodic stripping voltammetry at some modified carbon electrodes. Metal electrode detection sensitivity is enhanced through surface modification of working electrode (GCE). Heavy metals have the defined redox potential. A remarkable deal of efficiency with the electrochemical sensors can be succeeded by layering the surface of the working electrode with film of active electro-catalytic species. Usually, electro catalysts used for fabrication of sensors are surfactants, nano-materials, polymers, carbon-based materials, organic ligands and biomaterials.

Abstract:
Optically nonlinear polymers are attractive materials to be applied as active media in electro-optic devices. Polymeric multilayer structures, including an optically nonlinear waveguiding core, sandwiched between cladding layers and electrodes, have been produced. Monomode waveguides have been defined in the core of such multilayer structures. After electric field poling (156 V/µm) of the polymer core, r33 values up to 28 pm/V have been measured; to our knowledge the highest reported value thus far for an off-resonance electro-optic effect in polymers. Some devices have been made and tested. It may be expected that poling at higher field strengths will increase the polymeric device efficiency.

Abstract:
Electro-optic (E-O) polymers have drawn great interests in recent years because of their potential applications in photonics devices such as electro-optic modulators and switches, optical data storage and information processing1-2. Recent interests have been focused on the design and development of polymeric material systems (active and passive) with large E-O coefficients and high thermal, temporal, chemical and phtochemical stability3-8. The E-O response of a active polymer commonly arises from the electric field induced alignment of its second-order nonlinear optical (NLO) chromophore, either doped as a guest/host system or covalently bonded as a side-chain. Because of the strong interaction among the electric dipoles, the poled structure is in a meta-stable state; the poled NLO chromophores which possess large dipole moment will tend to relax back to the randomly oriented state. As a result, the stability of the poled structure strongly depends on the rigidity of the overall material system. This paper provides a brief review of the latest developments of highly efficient and thermally stable chromophores and polymers for device applications.
