摘要
讨论了PTFE复合膜防护机理及透湿影响因素.结果表明,PTFE薄膜和聚醚酯涂层对病毒防护起重要作用,微孔膜厚度、空隙率和孔径等结构参数对透湿影响小,但聚醚酯涂层的影响较大.采用PTFE复合膜对SARS等病毒具有较好的防护效果.
The protection mechanism of laminated textiles of PTFE comembrane was discussed. The results show that PTFE membrane and polyester ether coating have remarkable effect on protection,the structural parameter of PTFE membrane has little effect on water vapor permeability.
