Water pollution by toxic organic compounds is a problem and demand for efficient adsorbents for the removal of toxic compounds is increasing. In the present work, we studied the functionalization of SBA-15 materials via the co-condensation between an alkoxysilane and an organoalkoxysilane in the presence of P123 as structuring agent. Several types of ligands were used: 3-mercaptopropylmethyldimethoxysilane, N-[3-(trimethoxysilyl) propyl] aniline; aminopropyltrimethoxysilane; [aminoethylamino]-propyltrimethoxysilanes and [(2-aminoethylamino) ethylamino] propyltrimethoxysilanes. These materials exhibit BET surface area of 275–776 m2/g and total pore volume of 0.29–1 cm3/g, depending on the ligand types and contents. Elementary analysis results confirm the incorporation of both thiol and amine group in the materials. Batch adsorption studies shows that the adsorption capacity of phenol drifts on the amine and thiol functionalized SBA-15 is greater than that on pure SBA-15. A linear relationship was observed between the adsorption capacity and N/SiO2 ratio. It was shown that the presence of amine promotes interactions with water molecules, on the other hand, these results can also be explained by the basic behavior of N-functionalized materials.

Employing mass conservation, time-resolved dewetting experiments of thin polymer films allow to determine in real time the dynamic contact angle and the slippage length. Moreover, based on a systematic variation of interfacial properties of a polymer brush, dewetting makes it possible to calculate the force it needs to extract a single polymer chain from its own melt. In the visco-elastic regime close to the glass transition, the temperature and molecular weight dependence of the relaxation time of residual stresses resulting from film preparation by spin-coating can be obtained from the evolution of the shape of the dewetting rim. The presented examples demonstrate that dewetting represents a powerful approach for a sensitive characterization of rheological, frictional and interfacial properties of thin polymer films.

Synthetic Lignin-polysaccharide Complexes: Novel Bionanoparticles Inspired from Wood.

The lignified cell wall, that is the main component of wood and plant stems, is a complex and highly organized composite resulting from the coordination of several biosynthetic pathways controlled by numerous genes. The resulting final material is a composite material where stiff fibres (cellulose microfibril) are bound together by much softer glue (polysaccharide-lignin complex). Formation processes of this materials can be understood as the sum of physico-chemical events (diffusion process, self-assembly, formation of covalent and non covalent interactions) involving polymers carrying their own organisational information via their chemical structure designed by the genetic machinery. Thus, the elucidation of relationship between chemical structure and supramolecular assembly is required for extracting biomimetic principles for the design of new materials from renewable ressources. Here we present results about in vitro approaches to reproduce the formation of the polysaccharide-lignin complexes that is the soft glue embedding cellulose microfibrills. Lignin monomers were polymerized in presence of polysaccharide (xylans). The supramolecular organizations of the resulting nanoparticles were studied by transmission electron microscopy, light scattering, atomic force microscopy and fluorescent probes (1-3). Variation of the morphology and inner density were investigated as a function of the chemical structure of the precursors (xylans and lignin monomers). Results from static and quasi-elastic light scattering indicate a dense core surrounded by a soft corona. Such organization is also supported by AFM images of the particles spread on a mica surface. Indeed images display gaussian height profiles when a low tapping force is applied whereas the shape of height profiles obtained at a higher mechanical solicitation is irregular and sharp due to deformation of the particles resulting from the tip indentation. Significance of this result for the cell wall biosynthesis will be discussed together with the possibility to use these particles for encapsulation and molecular imprinting.

We studied the dewetting process of thin polystyrene (PS) films on silicon substrates, coated with a thin, irreversibly adsorbed polydimethylsiloxane (PDMS) layer, by optical microscopy and atomic force microscopy. Besides demonstrating the exceptional potential of dewetting for a sensitive characterization of rheological properties of PS thin films, characterized by a stress-relaxation time, τ1, we focused on the influence of the frictional behaviour (energy dissipation mechanism) at the interface between the PDMS-coated silicon wafer and the PS film on the dewetting process. Our results show that the initial stages of dewetting depend sensitively on the thickness and the way the PDMS layer was adsorbed. The maximum width of the dewetting rim at τ1 increased with increasing PDMS layer thickness, which can be interpreted as an increase of the effective, velocity-dependent slippage length. Interestingly, τ1 was found to be almost independent of the substrate properties. Our results demonstrate that dewetting is a really powerful approach for rheological and frictional studies of thin polymer films.

Performing detailed studies of viscoelastic dewetting of thin polystyrene films on solid substrates, we demonstrate the existence of residual stress due to strongly out of equilibrium chain conformations and a reduced entanglement density resulting from film preparation by spin coating. The ratio of stress over elastic modulus was found to increase strongly with decreasing film thickness and increasing chain length. Full equilibration of chain conformations required long times comparable to bulk reptation times. However, for chains longer than about 3000 monomers, the residual stress relaxed faster, at a rate independent of chain length.

The study of the dewetting of very thin polymer films has recently revealed many unexpected features (e.g. unusual rim morphologies and front velocities) which have been the focus of several theoretical models. Surprisingly, one of the most striking features, that is the decrease of the rim width with time, has not yet been explained. In the present letter, we show how the combined effects of a non-linear friction between the film and the substrate, and the presence of residual stresses within the film, result in the presence of a maximum in the time evolution of the rim width. Our model allows a quantitative evaluation of the residual stresses and a characterization of the friction between the polymer film and the substrate. In addition, we show how the introduction of a non-linear friction simply explains the experimentally observed rapid decrease of the dewetting velocity with time
