一般描述

聚乙烯醇(PVA)是一种线性亲水合成树脂,具有单斜晶体结构。它可以通过乙烯基酯或醚的聚合和之后的皂化或酯交换反应来合成。由于其良好的物理和化学性质, PVA 被广泛应用于粘合剂、纤维、造纸行业、药物递送和组织工程。

应用

PVA 用作生物试剂,以测试氧化锌纳米颗粒的分散。PVA 已被评估为有效的抗蛋白质材料。2 它可用于稳定直径 3-8nm 的金胶体。
聚乙烯醇可用作合成介孔沸石的辅助模板。

它可用于制备水凝胶模板以生产缓释给药的均质微颗粒。由于其高抗张强度和弹性,PVA可用作微颗粒制备中的稳定剂。

特点和优势

  • 良好的机械和化学 稳定性
  • 无毒
  • 亲水性可调节
  • 耐溶剂性 可形成薄膜
