Abstract: Waterproof and moisture permeable membranes are a kind of functional membrane material with both waterproof and moisture permeability. Combined with fiber fabric, they can prepare functional textiles with unique protective properties, waterproof, breathable and moisture permeability. Currently, the moisture and heat transfer membrane materials used in human-environment interaction of wearable textiles mainly include polytetrafluoroethylene hydrophobic membranes, polyurethane hydrophilic membranes and electrospun fiber membranes. Therefore, the structure, preparation method, waterproof and moisture permeable mechanism and application of these three kinds of waterproof and moisture permeable membranes are reviewed. The research progress of of waterproof and moisture permeable membranes and their application trend in textiles are introduced, and the research focus of the future development on intelligent fabrics is prospected. 

Key words: waterproofing and moisture permeability, functional membranes, intelligent fabric, electrospun fiber membrane, protective property

摘要： 防水透湿膜是一种兼具耐水渗透性和水汽透过性的功能膜材料，其与纤维面料复合，可制备具有独特防护性和兼顾透气、透湿于一体的舒适型功能性纺织品。目前，用于可穿戴纺织品的人体环境交互领域的湿热传输膜材料主要有聚四氟乙烯疏水膜、聚氨酯亲水膜和静电纺丝纤维膜。本文对这3种防水透湿膜的结构、制备方法、防水透湿机理及应用性等进行综述，总结防水透湿膜的研究进展及其在纺织上的应用趋势，并对未来智能防水透湿薄膜的研发重点做出展望。
