Texto completoDiazonium interface chemistry has progressed over the last few years and practically involved in all areas of materials science and engineering. The rationale for employing diazonium salts is that they attach to surfaces with remarkable bond energies, particularly on sp² carbon materials, making them an ideal coupling agent for polymers to surfaces In this context, novel CNT-polytriazole (CNT-PTAz) and CNT-dye nanohybrids were designed and thoroughly characterized. First, CNT-PTAz nanohybrid was prepared by click polymerization: multiwalled carbon nanotubes (CNTs) were modified with azidophenyl groups (CNT-N3) from 4-azidobenzenediazonium precursor and served as nanoscale platform for the surface confined polyaddition. The CNT-PTAz nanohybrid was characterized by TGA, XPS, IR, and Raman. The robust CNT-PTAz is robust and has potential in developing heavy metal adsorbents, nanosupport for catalysts or for gas storage. In the second major part, we grafted CNT with diazotized Neutral red (NR), Azure A (AA) and Congo Red (CR) dyes by simple, spontaneous reaction of the diazonium salts and CNTs in water, at RT. A thorough investigation of the nanohybrids showed that the adhesion is strong (CNT-dye C-C bond energy higher than 150 kJ/mol), and the layer is uniform. These nanohybrids further served to reinforce ethylene-vinyl acetate (EVA) an elastomeric matrix. The reinforced matrix is flexible and serves as optothermal actuators where the grafted dye catches the light to induce mechanical changes in the matrix monitored by dynamic mechanical analysis. CNT/dye-reinforced EVA is a promising flexible composite for developing new types of visual-aid tablet for visually impaired people. The versatile CNT-dye nanohybrids are also unique chemiresistive gas sensors for the molecular recognition of acetone vapours. In a final application, CNT-CR nanohybrid was investigated as an electrocatalyst for the Direct Oxidation of Methanol. Interesting results were obtained with these nanohybrids but significant improvements (3-fold) of the electrocatalytic properties were achieved with CNT-CR decorated with gold nanoparticles. The newly designed electrocatalytic system could be regarded for different promising applications most likely as for sensors, biosensors, heterogeneous catalysts for fuel cells and for nanotechnology To summarize, newly designed CNT-based nanohybrids have unique performances ascribed to the versatility of the diazonium interface chemistry in efficiently attaching functional molecular and macromolecular layers. The novel nanohybrids serve as building blocks for designing high performance nanocomposite materials relevant to challenging timely social economic issues, namely environment, biomedicine and energy

Texto completoCarbon nanoparticles are studied for their interesting properties in many application fields. This implies to understand and to characterise the specific properties of these nanoparticles. Laser pyrolysis is a versatile method for the synthesis of various nanoparticles and has been used successfully in the case of carbon nanoparticles. The aim of this work is to extend this research to the study of mixed carbon structures such as carbon/nitrogen or carbon/iron structures. These structures are indeed little studied and it is important to be able to determine the optimal experimental conditions to elaborate them by laser pyrolysis and to characterise their properties. In the case of carbon/nitrogen structures, we succeed in the incorporation of nitrogen in the powders in large amounts up to 20%. This high incorporation occurred by using a mixture of different gaseous precursors and allowed us to study the evolution of the structure as a function of the nitrogen incorporation rate in the powders. A comparative study between infrared spectroscopy and near edge x-ray absorption fine structure allowed to attribute the observed bands to an original structure. Indeed these bands could be explained by the interaction of a non bonding doublet of a nitrogen and the cn triple bond which can be present in two types of bondings : -c=n-cn or n-c=c-cn. For the carbon/iron compounds, this work showed how the laser pyrolysis of an aerosol mixture containing ferrocene leads to the synthesis of carbon nanopowders with different morphologies and structures. These powders contain always iron nanoparticles incorporated in the carbon matrix

Texto completoThe interest in carbon nanomaterials is expanding due to their potential for various applications. The network of sp²-hybridized carbon atoms, common to all materials of this family, generates excellent electronic and optical properties which are modulated by the shape, the size and the dimensionality of the carbon network. Among these nanomaterials, carbon nanoparticles (CNP) have a singular potential due to their photoluminescence properties, their photostability and their low toxicity. Accordingly, the application of CNP in biomedicine, optoelectronics and photocatalysis is greatly studied. However, the current synthetic methods and separation techniques represent limitations to their implementation. The use of high temperatures (>100 °C) hinders the precise control over shape and size of the CNP, the synthetic yields are low and the materials’ surface is chemically inert. In this project, the objective is to establish a route for CNP synthesis which surpasses the limitations of the current preparation methods. In other words, we are trying to develop a method allowing a precise control of the particles’ shape and size, while avoiding the use of high temperatures. The strategy is based on the dispersion polymerization of alkyne-rich organic units, used as a metastable carbon source. On one hand, the polymerization of alkyne-rich monomers allows the one-step synthesis of polyynes which, due to their instability, react spontaneously to produce a material composed mainly of sp²-hybridized carbon atoms. On the other hand, dispersion polymerization ensures a morphological control of the particles during their synthesis. Adding to the main objective, surface functionalization of the particles is intended by exploiting the reactivity of residual alkynes in the carbon structure. Also, we try to exchange the alkyne-rich monomer in order to improve the photoluminescence properties of the particles obtained from the developed process.

Texto completoAdditives with tribological action (MoDTC and ZnDTP) used at present are organic molecules containing sulphur and phosphorous. For environmental reasons, it is important to reduce or eliminate the presence of these two elements in oil. In this study, we are being interested in nanoparticles with closed structure (spherical, cylindrical) as potential substitutes of these additives. Their size, nanometric, enables them to enter easily the contact and their structure, closed, confers a great chemical inertia to them. Fullerenes of MS2 show very good friction reducing and anti wear properties. Their lubrication mechanism is based on the release of hexagonal MS2 sheets in the contact area. Tribological properties of carbon nanotubes depend on several parameters (number of wall, presence of catalyst). A structural modification of nanotubes inside the contact area is necessary

Texto completoThis work was performed in the framework of the European FP6 RTN CARBIO (www. Carbio. Eu) project, aiming at exploiting the potential of multi- functional DWNT and Carbon encapsulated metal nanoparticles for biomedical application, in particular to act as magnetic nano-heaters(cancer treatment by hyperthermia) or drug - carrier systems. To achieve these goals, DWNT have first been synthesised by catalytic chemical vapour deposition (CCVD) of a H2-CH4 mixture over (Mg, Co, Mo)O catalysts. In order to fill the empty cavity of DWNT with magnetic materials, the tips of the tubes have to be opened. The opening of DWNT was performed in different conditions using wet chemistry routes such as oxidation with HNO3, HNO3/H2SO4, KMnO4 or K2Cr2O7 or dry routes involving air oxidation or microwave heating. Due to drawbacks of some of the opening techniques (sample coating with amorphous oxidation debris), we have developed extra purification methods such as NaOH washing, oxidation in air or microwave heating. The filling of DWNT was performed using one-step (during the opening) or two-step (after the opening) methods in over-saturated iron (III) nitrate or iron (III) chloride solutions, in different conditions in order to assess the influence of stirring time, concentration and temperature. Control experiments of filling with uranium compounds were performed. A second strategy that we have developed in this work was the direct CCVD synthesis of carbon-encapsulated Fe, Co, Co/Fe and Ni nanoparticles. The encapsulated nanoparticles have been synthesized with gaseous mixtures of H2/CH4 or N2/CH4, using different MgO-based catalysts (Mg0. 95Co0. 05O, Mg0. 95Fe0. 05O, Mg0. 95Co0. 025/Fe0. 025O and Mg0. 95Ni0. 05O solid solutions). The obtained samples correspond for example to spherical and/or oblong carbon-encapsulated Co nanoparticles with size distribution 6-10 nm (60%) and 11-20 nm (40%). Oblong or spherical carbon-encapsulated nanoparticles were also observed with Fe and Co/Fe, with diameter within the range 1-10 nm (80%) and 11-30 nm (20%). The most promising material for hyperthermia application was found to be the carbon-encapsulated Co nanoparticles which showed the highest saturation magnetisation at room temperature (Ms) and the highest Specific Absorption Rate (SAR)

Texto completoThe association of nanoparticles with complementary properties is an interesting way to develop multifunctional original architectures. Our strategy consists in combining the ability of biosourced particles, the nanocrystals of celluloses (CNC), to form complex structures, with the properties of the single and multi-wall carbon nanotubes (CNT). Their non-covalent association aim is to preserve these properties and to realize oil-in-water Pickering emulsions and foams by freeze-drying. The aqueous dispersion of these nanoparticles shows high yields achieving as high as 70 % of dispersed NTC. The exploration of the various parameters controlling the dispersion (concentration of NTC and NCC, sonication time and power) and of the morphology of the hybrids (by electronic and atomic force microscopies) allow us to propose a quantitative model for the dispersion. These hybrids can also stabilize oil/water interface to form Pickering emulsion. Monodisperse distribution of micrometer-sized droplets is obtained. The addition of the NTC does not modify the morphology of the emulsion but improve their rheological properties. The freeze-drying of the concentrated emulsions produces solid foams with controlled structures. The porosity is determined during the step of emulsification. The mechanical and electrical properties show slight improvement by the addition of the NTC. We attribution these weak performance to the specific structure of the walls of the foams obtained by the alignment of the CNC weakly linked
