Abstract

In recent years, air filtration has been gaining much attention, and now people are much more concerned about antibacterial filters due to the spreading of COVID-19. The electret polypropylene (PP) nonwoven fabrics possess excellent filtration efficiency but a limited antibacterial effect against and , and therefore triclosan is used in this study. Serving as an antibacterial agent, triclosan with a low molecular weight is an effective additive for the test results, indicating that the presence of triclosan strengthens the antibacterial effects of the filters. In addition, triclosan also strengthens the PP's crystallinity, which in turn betters the filtration efficiency of the filters concurrently. Demonstrating powerful filtration and antibacterial performances, the antibacterial electret PP filters are highly qualified for filter applications.

摘要

近年来，空气过滤越来越受到关注，由于新冠病毒的传播，现在人们更加关注抗菌过滤器。驻极体聚丙烯（PP）无纺布具有优异的过滤效率，但对[具体细菌名称未给出]和[具体细菌名称未给出]的抗菌效果有限，因此本研究使用了三氯生。作为一种抗菌剂，低分子量的三氯生是测试结果的有效添加剂，表明三氯生的存在增强了过滤器的抗菌效果。此外，三氯生还增强了PP的结晶度，这反过来又同时提高了过滤器的过滤效率。抗菌驻极体PP过滤器展现出强大的过滤和抗菌性能，非常适合用于过滤应用。
