ZnO/PLA/PCL复合微纳米纤维膜表现出更好的抗菌效率。当ZnO 含量为10%(wt)时

复合微纳米纤维膜具有最佳的抗菌性能;药物释放性能结果表明

ZnO/PLA/PCL复合微纳米纤维膜具有良好的药物缓释性能。

Abstract

The antibacterial micro-nano fiber membrane loaded with zinc oxide (ZnO)/polylactic acid (PLA)/ polycaprolactone (PCL) was prepared by electrostatic spinning technology. And the surface morphology

elementary composition and chemical structure of the composite membrane were characterized by scanning electronic microscope (SEM)

X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR)

respectively. The antibacterial performance of the composite membrane was evaluated by the antibacterial experiment. The drug release behavior of the composite membrane

in vitro

was measured by ultraviolet spectrophotometer. The results showed that ZnO and LAH were successfully mixed into the composite micro-nano fibers by physical blending; Concerning to the antibacterial properties

ZnO/PLA/PCL micro-nano fiber composite membranes exhibited better antibacterial efficiency compared to the PLA/PCL micro-nano fiber composite membranes. When the ZnO content was 10% (wt)

the composite fiber membrane had the best antibacterial performance. The drug release performance results showed that the ZnO/PLA/PCL micro-nano fiber composite membrane had good drug release performance.
