Processable polyaniline/titania nanocomposites with good photocatalytic and conductivity properties prepared via peroxo-titanium complex catalyzed emulsion polymerization approach

► PTC was used as both the TiO2 precursor and the oxidant for the polymerization of PAni/TiO2 nanocomposites. ► Anatase TiO2 were well-dispersed in the PAni chains without aggregation. ► The TiO2 were anchored on the polymer chains through chemical interactions. ► The PAni/TiO2 composites could be well dispersed in common solvent, and showing good photocatalytic and conductivity properties.
