Preparation and Characterization of Chitosan-nanometer ZNO Composite Films
Nano-composite films have been widely used in many fields of microbial chemical industry.Chitosan-nanometer ZNO(ACS-ZnO)composite films were prepared by one-step precipitation,and their properties were characterized.The results show that the size of ACS-ZnO particles is relatively uniform,and spherical particles in the range of 100~200 nm are formed.The sharp peaks formed by ACS-zno samples correspond well to the standard peaks of ZnO,and ZnO particles can be effectively dissolved into ACS.The absorption peak of ZnO zinc particles is 372 nm,while that of ACS-ZnO particles is 361 nm,which significantly reduces the moisture absorption performance of the composite film.
