Abstract :Polyvinyl alcohol insert ignore into journalissuearticles values(PVA); composite films with different hemp protein particles insert ignore into journalissuearticles values(HPP); as additives were successfully synthesized by a solution casting method. The properties of HPP-based PVA composites films were investigated. The characterizations of pure PVA and PVA composite films were performed regarding Fourier transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR);, ultra-violet insert ignore into journalissuearticles values(UV-Vis); to investigate the chemical properties. The formation of hydrogen bond in the PVA-HPP films, which could improve the compatibility of the two components was investigated by FTIR spectroscopy and UV-Vis analysis. The overall results showed that a higher loading of HPP into the PVA matrix improved the chemical interactions significantly. The swelling degree decreased while the water contact angle values increased as the HPP content increased.
