以聚四氟乙烯(PTFE)为基料,添加3种不同种类的抗菌剂,制备了系列抗菌PTFE双向拉伸薄膜;并测定了薄膜对大肠杆菌、金黄色葡萄球菌、黑色芽孢变种以及白色念珠菌的抑菌性能;并测试了添加抗菌剂后对薄膜力学性能的影响。研究发现,添加编号为CAH-2的抗菌剂制备的薄膜抗菌效果均达到100%,具有广谱抗菌性。此外,添加液体抗菌剂会使薄膜的力学强度略有下降,添加固体粉末抗菌剂有助于增强薄膜的力学性能。
A series of antibacterial PTFE biaxially stretched films were prepared by using polytetrafluoroethylene (PTFE) as the base material and three different kinds of antibacterial agents by adding different antibacterial agents. The effects of the film on Escherichia coli, Staphylococcus aureus, The antibacterial activity of the bacteria was tested. The effect of antimicrobial agent on the mechanical properties of the film was also tested. The results showed that antibacterial agents added with CAH-2 were all antibacterial agents with antimicrobial activity up to 100%. In addition, the addition of liquid antibacterial agent will make the mechanical strength of the film slightly decreased, adding solid powder antibacterial agent helps to enhance the mechanical properties of the film.
