Growth of TiO2 Particles within a Polymeric Matrix


As a simple model for biomineralization we are investigating the deposition of oxide particles into polymers by the in situ hydrolysis of oxides. By light scattering and electron microscopy we have observed the development of titania in polyvinylchloride. Hydrolysis is due to exposure to atmospheric moisture after film formation under very dry conditions. We believe of alkoxide initially phase separate and then are hydrolysed. Using a strongly Aolymer as a matrix for silica formation we present evidence for catalysis of particle -tby the matrix.
