The films prepared by the electrophoretic sol-gel deposition are basically composed of monodispersed spherical particles, and have a lot of open spaces among these particles. If the open spaces are filled with some organic polymers, new type of inorganic-organic composite films with unique characteristics are expected to be obtained (Hasegawa, 1999). Silica particles are modified with 3-aminopropyltriethoxysilane (APS) and vinyltriethoxysilane (VTES). Smooth and crack-free films ca. 15 fim thick are obtainable when ASP-modified silica particles are used for cathodic deposition with addition of PEI. Thick films with reduced open spaces are obtained when VTES modified silica particles are co-deposited with polyethylene maleate. [Pg.315]
