Abstract

A wet layer-by-layer self-assembly of composite TiO₂/polymer films on Si and Al₂O₃/Al, substrates has been studied by AFM, STM, and ellipsometry techniques. The quality of the first adsorbed TiO₂ layer has been found to be the governing factor in multilayer film growth. The first layer consists of single particles and particle agglomerates 30-120 nm wide The surface coverage in the layer is determined by the chemical composition of the substrate surface and water pH in post-adsorption rinsing procedure. Well-packed TiO₂/polymer film completely covering the surface has been prepared in five adsorption cycle on Al₂O₃/Al substrate. The film remained crack-free after heat treatment at 300°C. I-V curves measurement reveals high resistivity (R ∼ 10¹⁰ O in the voltage range from in to +3 V) of TiO₂/polymer films prepared in ten adsorption cycles.
