Original Abstract

Mixtures of polymeric siloxane binder and titania were subjected to ball milling for variable time. After milling, they were spin-coated and inkjet printed onto soda-lime glass plates producing a titania-polysiloxane hybrid layers which were converted into titania-amorphous silica hybrid layers by thermal curing. Various experimental methods indicated that the ball milling process induced significant changes in the textural properties of the layer forming material. While some material properties and layer parameters show monotonous systematic decrease with milling time (particle size, surface roughness, layer thickness and haze), others show a maximum (specific surface area, photocurrent density). Thus by a careful control of the milling process we can adjust and optimize the performance of both powder and immobilized photocatalysts.
