摘要(Abstract)：

【目的】探究ZnO/Ag复合粒子(ZA)对基于羟乙基壳聚糖(HCS)的Pickering乳液的稳定效果,并通过静电纺Pickering乳液工艺优化制备包埋有茶树精油(TTO)的纳米纤维。【方法】以合成的ZA为稳定剂,研究ZA和TTO用量对HCS乳液稳定性的影响规律;以电压、聚乙烯醇(PVA)用量和接收距离为考察指标,优化纳米纤维加工工艺;以水蒸气透过法和滤纸片法研究所得纳米纤维的透气性能和抗菌活性。【结果】采用质量分数1.5%的ZA和体积分数60%的TTO,可获得最稳定的HCS乳液。最优的成丝条件为电压22kV、接收距离15cm、PVA质量分数10%,此条件下所得纤维的直径约为0.60μm,其对大肠杆菌和金葡菌的抑菌宽度分别为(16.97±0.09)和(15.97±0.11)mm,所得纤维膜的水蒸气透过率为0.21 g/(cm2·d)。【结论】通过ZA的稳定作用,可获得包埋TTO的HCS纳米纤维。
