Photocatalytic/biodegradable film based on carboxymethyl cellulose, modified by gelatin and TiO-Ag nanoparticles.

In this study, the composite of carboxymethyl cellulose (CMC) film modified with gelatin and TiO-Ag nanoparticles (CMC/Gel/TiO-Ag) was prepared and some properties of synthesized film including physicochemical and photocatalytic properties were investigated. FT-IR results showed that new interactions between the film components were created. Scanning electron microscopy (SEM) results showed that the TiO-Ag particles with 50-100 nm distributed in the CMC/Gelatin film.
