One-pot synthesis of hybrid TiO2–polyaniline nanoparticles by self-catalyzed hydroamination and oxidative polymerization from TiO2–methacrylic acid nanoparticles

A simple self-catalyzed hydroamination method for creating hybrid TiO(2)-polyaniline core-shell nanoparticles (NP) has been shown. Hybrid NPs with a range of possible sizes are afforded in high yield under mild reaction conditions and simultaneously show improved charge transport and electrochromic behavior compared to either polyaniline alone or physically blended with TiO(2).
