Effect of silver nanoparticles on the characteristic and properties of PVA/D-glucose/Agar film

Abstract

    In present work, we introduced silver nanoparticles (AgNPs) into PVA/D-glucose/Agar film for the purpose of enhancing mechanical behavior, hydrophobicity, and antibacterial activity of the resultant film. The PVA/D-glucose/Agar films loading AgNPs were prepared via facile casting method. The ATR-FTIR results demonstrated no chemical interaction between AgNPs and polymer component formulated in films and thus, the swelling degree and solubility of resulting film was not affected by the addition of AgNPs. More importantly, the antibacterial activity of film with loading AgNPs was significantly revitalized and therefore it is a potentially promising material ideally suitable for food packaging application.
