Abstract:
Periodic gyroid network materials have many interesting properties (band gaps, topologically protected modes, superior charge and mass transport, and outstanding mechanical properties) due to the space-group symmetries and their multichannel triply continuous morphology. The three-dimensional structure of a twin boundary in a self-assembled polystyrene-b-polydimethylsiloxane (PS-PDMS) double-gyroid (DG) forming diblock copolymer is directly visualized using dual-beam scanning microscopy. The reconstruction clearly shows that the intermaterial dividing surface (IMDS) is smooth and continuous across the boundary plane as the pairs of chiral PDMS networks suddenly change their handedness. The boundary plane therefore acts as a topological mirror. The morphology of the normally chiral nodes and strut loops within the networks is altered in the twin-boundary plane with the formation of three new types of achiral nodes and the appearance of two new classes of achiral loops. The boundary region shares a very similar surface/volume ratio and distribution of the mean and Gaussian curvatures of the IMDS as the adjacent ordered DG grain regions, suggesting the twin is a low-energy boundary.

Abstract:
We report on formation of a bicontinuous double gyroid phase by a wedge-shaped amphiphilic mesogen, pyridinium 4′-[3″,4″,5″-tris-(octyloxy)benzoyloxy]azobenzene-4-sulfonate. It is found that this compound can self-organize in zeolite-like structures adaptive to environmental conditions (e.g., temperature, humidity, solvent vapors). Depending on the type of the phase, the structure contains 1D, 2D, or 3D networks of nanometer-sized ion channels. Of particular interest are bicontinuous phases, such as the double gyroid phase, as they hold promise for applications in separation and energy. Specially designed environmental cells compatible with grazing-incidence X-ray scattering and atomic force microscopy enable simultaneous measurements of structural parameters/morphology during vapor-annealing treatment at different temperatures. Such in-situ approach allows finding the environmental conditions at which the double gyroid phase can be formed and provide insights on the supramolecular structure of thin films at different spatial levels.

Abstract:
The objective of this work, concerning the template-assisted patterning of functional materials on the nanoscale to enhance specific material properties, is five-fold. Firstly, to develop a highly reproducible synthesis pathway for large quantities of double- gyroid-forming diblock copolymers. Secondly, to replace the previously used fluo- rinated monomers with an inexpensive and environmentally sustainable alternative making large-scale applications feasible. Thirdly, to establish a reliable and fast fabri- cation technique for fully porous gyroidal templates. Fourthly, to replicate these tem- plates with inorganic as well as organic functional materials using electrochemical and atomic layer deposition. Finally, to apply and characterize these novel double-gyroid- structured materials in devices such as photovoltaic devices, electrochromic displays, and supercapacitors. The first part of this thesis introduces the different techniques of modern nanotechnol- ogy employed in three-dimensional nanopatterning of functional materials and seeks to highlight the possibilities and advantages of using self-assembled, mesoporous polymeric templates for this purpose. Chapter 2 explores the fascinating gyroidal intermaterial dividing surfaces formed by self-assembling systems, such as microphase separating di- block copolymers. Chapter 3 focuses on the synthesis of double-gyroid-forming diblock copolymers consisting of poly(4-X-styrene) and poly(lactic acid) via atom transfer radi- cal and organocatalytic ring-opening polymerization using a bifunctional initiator. The preparation of mesoporous templates with double-gyroid morphology based on a rapid thermal annealing protocol is described in Chapter 4. Importantly, it is shown that copolymers prepared from inexpensive, non-substituted styrene can yield fully porous thin films. Chapter 5 reports the template-assisted electrodeposition of metal oxides, such as V2O5, using the previously prepared voided styrenic templates. Further, the perfor- mance of these materials as electrodes in electrochromic displays and supercapacitors is tested. Chapter 6 describes an alternative approach to obtain double-gyroid-structured metal ceramics via the post-nanostructuring thermal oxidation of electroplated metals. Nickel is chosen to demonstrate this highly versatile fabrication route and to study the nanoscale Kirkendall effect of three-dimensional structures. Further, the electrochromic performance of NiO is investigated. Chapter 7 deals with yet another electrodeposition technique, namely the electropolymerization of conjugated polymers. Identification of suitable solvents for the templated electrosynthesis and the subsequent template dis- solution enable the three-dimensional nanopatterning of PPy, PEDOT, and PT. The refilling of the organic template via atomic layer deposition, including the necessary chemically modification of the styrenic scaffold for an improved thermal resistance and surface functionality, is discussed in Chapter 8.

Abstract:
碩士<br>國立清華大學<br>光電工程研究所<br>105<br>Gyroid is a type of three-dimensional chiral structure that has been found in many insect species. Due to the periodic and chiral structure, the gyroid has been shown to exhibit photonic band gap and circular polarization dependent characteristics. Previous results show that the optical properties of the double gyroid can be tuned by refractive index contrast of the constituent materials or the volume fraction. However, double gyroid structures are mainly studied based on one constituent material, either dielectric or metal. The influence of different materials on the optical properties of double gyroid has not been explored. In this work, we investigate the polarization-dependent characteristics of a hybrid metal/dielectric double gyroid based on finite-difference time domain (FDTD) method. The corresponding band structure, transmission spectra, CD indices and coupling indices are calculated to examine the existence of polarization band gap and complete band gap in a metal/dielectric double gyroid. The evolution of band gaps with respect to different fractions of the hybrid system are presented. Furthermore, the dispersion surfaces and equifrequency contours (EFCs) are analyzed in the hybrid double gyroid. Based on the dispersion characteristics, anomalous guiding characteristics including negative refraction and collimation effect are discussed. These results could be of great interests for the design of function of circular-polarization devices based on hybrid metal/dielectric double gyroid structures.

Full text
Abstract:
碩士<br>國立清華大學<br>化學工程學系<br>104<br>In this study, by taking advantage of the nucleation and growth control of templated electroless plating, a novel approach to fabricate metallic materials with single gyroid (SG) texture using polymer template with double gyroid (DG) texture is suggested. Nanoporous polystyrene (PS) with DG texture is prepared from the self-assembly of polystyrene-b-poly(L-lactide) (PS-PLLA) followed by hydrolysis of PLLA block, and then used as a template for templated electroless plating. With pore-filling of the dilute Pd solution to the PS template, homogeneously distributed Pd clusters within the PS template can be prepared by using hydrazine for the reduction of Pd ions, giving one single Pd nuclei for the growth of SG-structured Ni. Subsequently, the Ni deposition using the Pd nuclei as catalytic site can be carried out to form SG-structured Ni. Finally, nanoporous Ni with SG-structured texture can be obtained after removal of the PS template by washing with dichloromethane. With the novel approach, SG-structured Ni with controlled particle radius from hundreds nm to micrometer can be prepared by tuning the growth time for the Ni deposition. Furthermore, tunable lattice constant of the SG-structured Ni and the corresponding filling ratio of the nanoporous Ni can be created from the pre-synthesized PS template with different molecular weights and compositions. To effectively achieve versatile purposes for optical applications, SG-structured Au is synthesized via the novel method as described above. As a result, this approach develop a platform technology to fabricate SG-structured metallic nanomaterials with versatile characteristic for novel properties from the nucleation and growth of templated electroless plating using self-assembled DG-structured block copolymers (BCPs) as templates.

Abstract:
碩士<br>國立清華大學<br>化學工程學系<br>101<br>Functionalized nanoporous materials with high porosity and high specific surface area have become promising materials for appealing applications. Gyroid phase with ordered, bi-continuous networks in 3D space is one of the most appealing morphologies for practical applications due to its high specific interfacial surface area. In this study, we aim to fabricate nanoporous gyroid SiO2 materials from templated sol-gel reaction using degradable block copolymer with gyroid-forming nanostructure as a template, and then to functionalize the nanoporous materials using “smart” polymer, poly(2-dimethylaminoethyl methacrylate) (PDMAEMA), brushes via “grafting from” method to give double stimuli-responsive properties. By taking advantage of the environmental stimuli, both thermal and pH, the pore features can be well defined by stretching and re-coiling of the grafted PDMAEMA brushes because of their adjustable chain conformation with reversible character. The grafting PDMAEMA on the inner wall of the nanoporous materials is evidenced by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The responsive properties with respect to environmental stimuli can be successfully traced by temperature-resolved small angle X-ray scattering (SAXS) in aqueous environment. Owing to the high specific surface area, 3D pore network, biocompatibility and environmental response, the functionalized nanoporous gyroid SiO2 are further demonstrated as stimuli-responsive controlled release system. As a result, the nanoporous SiO2 with tunable pore size can be fabricated to give promising properties for various applications, such as environment-selective delivery systems, bio-mimetic on/off gates, and specific environmental detectors.

Abstract:
Block copolymer consists of two or more long blocks with dissimilar chemical structures which are chemically connected. There are different architectures of block copolymers, namely, AB-type diblock, ABA-type triblock, ABC-type triblock, and AmBn radial or star-shaped block copolymers, as shown schematically in Figure 8.1. The majority of block copolymers has long been synthesized by sequential anionic polymerization, which gives rise to narrow molecular weight distribution, although other synthesis methods (e.g., cationic polymerization, atom transfer radical polymerization) have also been developed in the more recent past. Owing to immiscibility between the constituent blocks, block copolymers above a certain threshold molecular weight form microdomains (10–50 nm in size), the structure of which depends primarily on block composition (or block length ratio). The presence of microdomains confers unique mechanical properties to block copolymers. There are many papers that have dealt with the synthesis and physical/mechanical properties of block copolymers, too many to cite them all here. There are monographs describing the synthesis and physical properties of block copolymers (Aggarwal 1970; Burke and Weiss 1973; Hamley 1998; Holden et al. 1996; Hsieh and Quirk 1996; Noshay and McGrath 1977). Figure 8.2 shows schematically four types of equilibrium microdomain structures observed in block copolymers. Referring to Figure 8.2, it is well established (Helfand and Wasserman 1982; Leibler 1980) that in microphase-separated block copolymers, spherical microdomains are observed when the volume fraction f of one of the blocks is less than approximately 0.15, hexagonally packed cylindrical microdomains are observed when the value of f is between approximately 0.15 and 0.44, and lamellar microdomains are observed when the value of f is between approximately 0.44 and 0.50. Some investigators have observed ordered bicontinuous double-diamonds (OBDD) (Thomas et al. 1986; Hasegawa et al. 1987) or bicontinuous gyroids (Hajduk et al. 1994) at a very narrow range of f (say, between approximately 0.35 and 0.40) for certain block copolymers. Figure 8.2 shows only one half of the symmetricity about f = 0.5. Transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), and small-angle neutron scattering (SANS) have long been used to investigate the types of microdomain structures in block copolymers.

Abstract:
Abstract A System of Arbitrary General Equations, SAGE, is a new mathematical description technique for modeling generic nonlinear systems with similar ease to linear approximation techniques but capturing data normally only obtainable through intensive nonlinear solving techniques. In this study, SAGE predicts the frequency response of fifteen manufactured nonlinear harmonic mechanical systems, categorized as an eccentric rotor system, and a horizontal pendulum system, all sprung with double spiral torsional springs additively manufactured in PLA, chosen for its nonlinear stress-strain material properties, with solid concentric, hollow, aligned rectilinear, honeycomb, and gyroid infill patterns, chosen to introduce a nonuniform spring geometry. Nonuniform spring geometries and nonlinear material properties give rise to nonlinear spring rates. The nonlinear harmonic mechanical systems are subjected to a cyclic forcing equation sweeping the frequency range of 0 Hz to 2 Hz to obtain a frequency response plot. ANSYS Multiphysics Engineering Simulation software was used to plot the frequency responses of the nonlinear harmonic mechanical systems modeled as a double spiral torsion spring attached to a point mass representing the properties of the physical system. The ANSYS, SAGE, and experimentally obtained frequency response plots are compared to demonstrate the ability of the developed model to display nonlinear behaviors effectively.

Full text
Abstract:
We describe and demonstrate a new type of phase-conjugate fiber-optic gyro1 (PCFOG). PCFOGs use phase conjugation to compensate for reciprocal phase changes due to thermal and mechanical effects on the fiber, while at the same time allowing for the measurement of the nonreciprocal phase shift produced by rotation. Where the best standard fiber-optic gyros require polarization-preserving fibers and couplers to avoid polarization scrambling that is a source of noise and signal fading, PCFOGs can avoid this problem by using polarization-preserving phase conjugation.2 This has the advantage of allowing for the use of inexpensive nonpolarization preserving and even multimode fibers and components. The double PCFOG is simply an interferometer, in which both arms contain fiber-optic coils terminated by the same self-pumped phase-conjugate mirror. We have recently demonstrated rotation sensing using such an interferometer with a self-pumped crystal of barium titanate as the phase-conjugate mirror. For this demonstration, the entire interferometer was mounted on a rotary table and light was piped to the table using a fiber optic. In addition to the simplicity of the new self-pumped version of the PCFOG, it has the advantage of allowing for the use of fiber-optic coils that are longer than the coherence length of the laser to increase the sensitivity of the gyro.

Abstract The concept of a new piezoelectric actuator design is the focus of an ongoing smart structures research at DLR. It envisages actuator geometries, that have their template in nature and are aimed at optimally transfering their mechanical power to the structure in which they are integrated. The second aspect can only be achieved in case of an impedance matching. We found out, that these very specific designs have highly interesting differential geometry descriptions and that these geometries can be realized in a congenial combined manufacturing procedure: we start with 3D-printed filigree lightweight structures and continue with self-organizing processes. The results are simply, doubly and triply periodic piezoelectric membranes, grids and truss elements. One of their essential properties is their almost perfect stress distribution under mechanical loads. Any notch stresses are prevented. In this paper the first example is the modified catenoid piezoactuator. We continue with a doubly periodic honeycomb structure and finish with triply periodic modified gyroid and diamond-like actuators.

Full text
Abstract:
When two phase-conjugate mirrors with gain are placed near each other, an oscillation will build up between them. This is called a double phase-conjugate oscillator (DPCO). DPCOs have many interesting physical properties that can be used to make sensors. For example, the frequencies of the counterpropagating oscillations in a linear DPCO are independent of the reciprocal optical path length of the resonator and dependent on the nonreciprocal optical path length. This is the exact opposite of linear oscillators using conventional mirrors (i.e., lasers). Since inertial effects produce nonreciprocal phase shifts, the DPCOs can be used to sense motion. In fact, the DPCO is the only oscillator that is known to be capable of measuring translation. Although conventional optics can be used to make rotation sensing oscillators (i.e., ring laser gyros), these devices cannot use solid-state gain media due to gain competition, and they suffer from the problem of frequency locking. These problems do not exist in phase-conjugate oscillators.
