Preparation, Characterization, and Antibacterial Activity of ZnS-NP’s Filled Polyvinylpyrrolidone/Chitosan Thin Films

Abstract

Semi-natural polymeric Polyvinyl pyrrolidone/Chitosan (PVP/CS) blend containing gradient concentrations of ZnS nanoparticles (ZnS-NPs) were prepared using a simple casting route and characterized by using XRD, TEM, and FTIR analysis. The XRD diffraction peaks of the prepared samples show no distinct sharp bands that lead to the amorphous and homogeneous distribution of ZnS-NPs inside the polymer composites. The TEM analysis showed the creation of ZnS nanoparticles of about uniform size and shape. Fourier transform infrared measurements (FTIR) take into account a detailed description of the different reaction mechanisms within the polymeric matrices.
