一般描述

聚乙烯醇(PVAc)是一种非结晶的无规立构聚合物。它是由乙酸乙烯酯单体通过自由基聚合来制备。由于其低毒性和良好的弹性,它常被用于食品行业。PVAc膜可用作载体和口服药物的发射传感器。

应用

聚乙烯乙酸酯可用作:
  • 制备气体和湿度传感器应用中聚合物纤维的起始原料。 柠檬酸掺杂的PVAc纳米纤维垫可用于开发室温下检测三甲胺气体的传感器。
  • 具有控释给药性能的漂浮片的聚合物涂层。 PVAc是一种赋形剂,可以确保可靠安全的药物释放。由于聚乙烯乙酸酯涂层的低固有密度和高弹性,PVAc-基骨架片可以流动。
它也可用于通过CNF的悬浮液与PVAc和聚乙烯醇溶液的简单混合来制备纤维素纳米微纤丝(CNF)-PVAc 纳米复合粘合剂。CNF的加入改善了纳米复合材料的机械性质。
