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。

Cellulose nanofibrils/polyvinyl acetate nanocomposite adhesives with improved mechanical properties.
Ons Chaabouni et al.
Carbohydrate polymers, 156, 64-70 (2016-11-16)
Cellulose nanofibrils (CNFs) are nanoscale cellulose produced from renewable resources with strong reinforcing potential when included in a polymer matrix. In this work, the effect of the addition of CNFs on the properties of waterborne polyvinylacetate (PVA) adhesive was investigated.
