摘要
采用静电纺丝方法制备不同质量混比聚乳酸(PLA)/透明质酸(HA)复合纤维膜。借助扫描电子显微镜(SEM)观察不同溶液性质条件下纤维形貌的变化。通过红外光谱(FT-IR)测试,表明复合薄膜中HA的存在以及溶剂的残留。抗菌测试结果显示,HA的加入在一定程度上改善了纯PLA纤维膜的抗菌性能,且随着HA含量的增加,抗菌率逐渐提高,当PLA/HA两者质量混比为90/10时,抗菌率从19.4%提高到47.8%。
Poly(lactic acid)(PLA)/hyaluronic acid(HA)composite fiber films with different mass ratios were prepared by electrospinning.The changes of fiber morphology under different solution properties was observed by scanning electron microscope(SEM).The existence of HA and residual solvent in the composite film were determined by FT-IR.The antibacterial test results showed that the antibacterial properties of pure PLA fiber membrane were improved with the addition of HA.The improvement of antibacterial effect was the most obvious when the mass ratio of PLA/HA was 95/5.The antibacterial rate was 76.4%.
