Inorganic film formers. Material and use

The paper aims to get in evidence some aspect of the synthesis and the use of sol-gel materials as film formers. Silica molecules modified with hydrocarbon chains carrying halogen atoms (F), aromatic function (C6H4;5) achieve a very impressive variety of applications. While the silica chemistry has been studied by long time, the sol-gel process get a new vitality from the better understanding of the microscopic structural changes induced by the different organic modified silica compound (chemical changes), by the addition of functional molecules and by the choice of solvents for the reactions and the application of the material before the use. From this point of view is very imperative to establish the kinetic of the hydrolysis and condensation reaction. The understanding of the possibility to use silica organically modified polymer as film formers is a interesting field where chemistry, material science, technology of the application and industrial constraints get together. The paper is the first from a study devoted to design sol-gel pigmented formulations for metal surface and we try to organise the enormous number of information on the sol-gel dispersion.
