Investigation of polypyrrole/polyvinyl alcohol-titanium dioxide composite films for photo-catalytic applications

- The study provides an easy and convenient method to fabricate films, which will give guidance for the preparation of three-dimensional materials.
- The PPy/PVA-TiO2 films can keep better photo-catalytic activities both under UV and visible light irradiation when compared with TiO2 film.
- There exist electron transfers between PPy/PVA and TiO2.
