使用氧化石墨烯（GO）制备GO-氧化锌（ZnO）。 利用表面上的羟基引发1-丙交酯开环聚合。 制备了接枝到GO-ZnO表面的聚（1-丙交酯）（PLLA）链GO-ZnO-PLLA的复合材料。 结果表明，本研究所采用的方法可一步、快速将PLLA接枝到GO-ZnO表面。将GO-ZnO分在至有机溶剂中以改变GO表面的化学结构，从而增强了GO-ZnO在PLLA基体中的分散和与PLLA的界面结合。随后，制备了

使用氧化石墨烯（GO）制备GO-氧化锌（ZnO）。 利用表面上的羟基引发1-丙交酯开环聚合。 制备了接枝到GO-ZnO表面的聚（1-丙交酯）（PLLA）链GO-ZnO-PLLA的复合材料。

结果表明，本研究所采用的方法可一步、快速将PLLA接枝到GO-ZnO表面。将GO-ZnO分在至有机溶剂中以改变GO表面的化学结构，从而增强了GO-ZnO在PLLA基体中的分散和与PLLA的界面结合。

随后，制备了复合膜GO-ZnO-PLLA和GO-ZnO-PLLA/PLLA。探究界面性质和机械性能的变化。 此外，研究人员还探究了纳米ZnO的抗菌性能。
