The adhesion and antimicrobial properties of nano silver/chitosan composite membrane in orthogonal research

摘要

Research the nano silver and other composite materials with the chitosan in the best composition with orthogonal test method. According to the best use concentration of nano silver and composite materials carry out the orthogonal experiment. By using the ultrasonic method test the adhesion strength between chitosan membrane and the breeding net through calculating the loss of the membrane. With bacteriostatic circle method to determine the bacteriostatic effect of membrane. The results show that the main factors influence the adhesion of membrane and the effectiveness of bacteriostatic is adhesives and Nano silver. The orthogonal experiment results show that the optimum conditions of film forming as follows: the adhesion agent A3%, adhesion reagent B3%, nano silver solution 2% nano antibacterial powder 3%, tea saponin solution 60 mg/L. Under these conditions, the loss of the membranewas14.6%, the inhibition zone was 2.35cm. Orthogonal test was applied to the ratio of composite materials can get the best composite columns. Creating a better performance of target product and has a promising prospect for practical application.
