一般說明

固相的聚(2-羟乙酯甲基丙烯酸)(pHEMA)是脆性的，而pHEMA水凝胶是一种软材料。pHEMA水凝胶的玻璃化转变温度可通过增加基质中水的含量而降低。 pHEMA的大分子属性是通过聚合物链以及水合水分子之间氢键的非共价相互作用而得以表征的。每一重复单元上羟基和羧基极性基团的存在使得该聚合物可与水相容。骨架上的疏水a-甲基可将水解稳定性传递给聚合物并提高聚合物基质的机械强度。

應用

pHEMA骨架被用于组织工程中。它可作为金属离子的吸附剂被用于生物医学应用的水凝胶中。pHEMA已被用于如软性隐形眼镜、药物输送系统和肾脏透析膜等应用中。pHEMA的纳米粒子可作为抗癌和抗肿瘤药物的一种受控输送载体。
