Abstract
The surfaces of titanium oxide nano-crystals were modified with γ-aminopropyl-triethoxy silane and N-phenyl-γ-aminopropyl-trimethoxy silane. Polymerizations of aniline on the modified titanium oxide nano-crystals were conducted. The composites were characterized by FTIR, ESCA and TEM. FTIR spectra indicate the formation of polyaniline. ESCA spectra of the composites show peaks of N with similar environment of N in polyaniline indicating the formation of polyaniline on the surface. The shape of the particles in the composite is spherical which is different from that of titanium oxide crystal and fibular structure of polyaniline polymerized under the same condition.
