摘　　要：为了提高聚二甲基硅氧烷(PDMS)膜的渗透汽化性能,采用一锅法制备PDMS-PMA半互穿聚合物网络结构(semi-IPN)渗透汽化膜,通过红外光谱和扫描电镜对其进行表征,并探究其溶胀性能和渗透汽化性能。结果表明,IPN结构的形成明显提高了PDMS膜的渗透汽化性能;在原料液温度为70℃、PMA含量为10%时,semi-IPN渗透汽化膜的分离因子为42.0、总通量为923g·m^-2·h^-1。In order to improve the pervaporation performance of polydimethylsiloxane(PDMS)membrane,we prepared PDMS-PMA(polymethyl acrylate)semi-interpenetrating polymer network(semi-IPN)pervaporation membranes by a one-pot method,characterized their structures by FTIR and SEM,and evaluated the swelling and pervaporation performance.The results show that the formation of IPN structure significantly improves the pervaporation performance of PDMS membrane.When the feed temperature is 70℃and the PMA content is 10%,the separation factor and the total flux of semi-IPN pervaporation membrane are 42.0 and 923 g·m^-2·h^-1,respectively.
