Solvent Effect of the Adsorption of Titanium Dioxide Nanoparticles onto Microporous Polymer Films

Abstract

We prepared honeycomb films of a crosslinkable poly(maleic anhydride-co-styrene). It was found that the surface modification of the polymer by ethanolamine had a profound effect on the adsorption of TiO₂ nanoparticles from alcoholic suspensions. The other important parameter to control adsorption density of the TiO₂ film on the honeycomb substrate was the water content of the alcohol. Furthermore, we found that other organic solvents can also be used to form adsorbed films with various morphologies. After pyrolysis, the microscopic honeycomb morphology was retained.
