| 摘 要： | 改性低温ＰＶＡ／ＰＡＭ（聚惭烯醇／丙烯酰胺）复合膜较低温ＯＶＡ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络结构，因此ＰＶＡ与ＰＡＭ的交联都可制约小分子这膜的速度。

| Abstract: | 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. |
