【Abstract】 The nanofiber is prepared by electrospinning technique in this paper. The porosity of nanofiber is calculated. Besides, the microstructure of nanofiber is observed using scanning electron microscope. The relationship between permeability and porosity is discussed. It is shown that permeability of nanofiber increases with the increase of porosity. The aims of this study is to establish the foundation of theory and technology for developing functional clothing and designing highly efficient filter system.更多还原
