中文摘要：

使用静电纺丝技术制备了纳米纤维,然后计算了纳米纤维的孔隙率,接着采用扫描电子显微镜观测了纳米纤维的微观结构,最后讨论了纳米纤维的渗透率与孔隙率的函数关系,研究结果表明,纳米纤维的渗透率随孔隙率的增加而增加。该研究为功能性衣服的开发和高效过滤系统的设计奠定理论和技术基础。

英文摘要：

The nanofiber is prepared by electrospinning technique in this paper. The porosity ofnanofiber is calculated. Be-sides, the microstructure ofnanofiber is observed using scanning electron microscope. The relationship between permeability andporosity is discussed. It is shown that permeability ofnanofiber increases with the increase of porosity. The aims of this study is to es-tablish the foundation of theory and technology for developing functional clothing and designing highly efficient filter systerrr
