Abstract :
In this article, the performance for nuclear, chemical and biological(NBC) filter applications of two filter media, microfiber and nanofiber, are compared. High filtration efficiency is needed for protection against airborne high-toxic particulate matter such as bacteria, viruses, chemical weapon agent(CWA) liquid aerosols and radioactive fine particles. Filter media based on micro glass fibre is widely used in NBC filters. Polymer based nanofibre composites are new candidates for filter media with high or ultra-high filtration efficiency. They offer many new and useful properties, but they also have some serious limitations in performance.
