一般描述
聚乙烯醇（PVA）是一种线性 亲水性合成聚合物，其主链仅由碳原子组成。 由于其惰性和稳定性，它被认为是安全和生物相容的。 它在厌氧和好氧条件下都是可生物降解的。由于 其独特的粘附性、安全性、强度、 成膜性、溶胀性和非致癌性等特性，它被广泛应用于 纸张、粘合剂、食品、生物医学和制药行业。部分水解的 PVA（87–89%）更易溶于水，并且对疏水表面具有更大的柔韧性和粘附性。
应用
PVA 对于 用于药物递送系统的聚合物具有显著的性能，例如高 表面稳定性和低蛋白质吸附。PVA 用在固体 分散体中防止晶体形成并提高药物溶解度。 它也可以用作造粒液，以防止晶体生长和 成核缓慢。与它的共聚物一起，它可以用于 亲水性和疏水性药物。 PVA 水凝胶和 微粒可用于癌症药物的药物输送系统。
PVA 可作为 表面稳定剂用于制备四环素缓释药物递送 载体。
高浓度藻酸盐/聚乙烯醇 （PVA）生物墨水可用于制备 3D 生物打印多孔支架。PVA 溶胶 从印刷支架的部分扩散产生了大量的于大量样品的并行测试。 微孔。
PVA 也可以作为水溶性聚合物模板， 通过原位聚合合成纳米聚吡咯。PVA 在水中产生稳定的聚吡咯纳米球分散体，纳米球的大小 取决于 PVA 的分子量和浓度。
