UV-Induced reduction of graphene oxide in cellulose nanofibril composites

We report on an effective dry method to reduce graphene oxide (GO) in films of cellulose nanofibrils (CNF) by UV irradiation in the presence of nitrogen gas. The reduction of GO and the removal of carbonyl and carboxyl moieties were confirmed by infrared and UV-vis spectroscopy, potentiometric charg...
