GLEANABLE AND SUNLIGHT-TOLERANT MULTIFUNCTIONAL NANOFIBROUS FILTER FOR WATER AND AIR FILTRATION AND FABRICATION PROCESS OF NANOFIBROUS FILTER THEREOF

摘要

This invention related to multifunctional nanofibrous filters for water and air microfiltration able to be reused several times and their fabrication process. The described nanofibrous filters have antibacterial, water repellent, anti-UV functions with high flexibility and tensile strength. The filters are able to be cleaned and dried under sunlight several times. The filter according to this invention can be fabricated by solution-based processing from specific chemical components via needle-based electrospinning, nanospider electrospinning or forced/centrifuge spinning. The nanofibrous filters have small pores, high surface area and porosity and show high efficiency toward microparticle filtration.
