NANOCOMPOSITE-NANOFIBER AND FILTER ELEMENT FOR NANOFIBER-AIR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a new nanocomposite-nanofiber, and a new filter element for a nanofiber-air filter.SOLUTION: When forming a nanofiber by using a spinning solution of polyether sulfone with an electrospinning method, a powder of a scallop is added to reduce a diameter of a nanofiber formed from polyether sulfone and produce the nanofiber having a small fiber diameter distribution. When the obtained nanocomposite-nanofiber is used for a filter element for a filter, a high-functional nanofiber-air filter that has low pressure loss, high particle trapping efficiency and a high bacteriostatic activity value is obtained.
