Preparation and Characterization of Ultrasound Treated Polyvinyl Alcohol/Chitosan/DMC Antimicrobial Films
Source abstract
Abstract
In this research, chitosan (CS) and poly (vinyl alcohol) (PVA) were adopted as a material, methacryloyloxyethyl trimethyl ammonium chloride (DMC) was added in various concentrations and was treated ultrasonically for the formation of films with the use of the polymer blending method. The influences exerted by the ultrasonication period on PVA/CS/DMC antimicrobial active materials underwent material characteristic tests. The consequences revealed that at the break of the compound films, ultrasonication raised the elongation and tensile strength on the whole. Ultrasonication further or also enhanced the light transmittance performance and composite films’ barrier property. Furthermore, the compound film with a DMC concentration of 2% had good antibacterial properties, the film’s inhibition rates against Staphylococcus aureus and Escherichia coli after ultrasonication were 79.23% ± 1.92% and 72.31% ± 1.35%, respectively.
