摘要 改性低温PVA/PAM (聚乙烯醇 /聚丙烯酰胺 )复合膜较低温PVA膜机械强度更好 .PAM掺入PVA后并不影响PVA的低温结晶过程 ,低温PVA/PAM的性能相似于低温PVA膜 .由于PVA/PAM复合膜是PVA物理交联与PAM化学交联的互穿网络结构 ,因此PVA与PAM的交联都可制约小分子透过膜的速度 . Modified subcooled PVA/PAM composite membrane is better than subcooled PVA membrane .PAM can not change PVA crystalling when it is added. The properties of subcooled PVA/PAM membrane is similar to subcooled PVA membrane. PVA/PAM has the structure of interacting penetrating net. So either PVA crosslinking or PAM crosslinking can control the speed of small molecular penetrating the membrane.
