摘　　要：为提升聚乙烯吡咯烷酮(PVP)的抗菌性能,将天然抑菌剂芦荟(Aloe)负载在PVP中,通过静电纺丝法制备不同质量比的PVP/Aloe复合纳米纤维膜。借助扫描电子显微镜、傅里叶变换红外光谱仪、接触角分析仪、表面张力计对该复合纳米纤维膜的形态、亲(疏)水性、粒径和基团结构进行表征与分析。结果表明:由于芦荟与PVP之间相互的物理作用,使制备的纳米纤维膜呈现相互分开又相互黏连的油条状结构,当PVP与芦荟的质量比为10∶4时,形成的油条状结构最为明显;PVP/Aloe复合纳米纤维膜对金黄色葡萄球菌具有抑菌作用,抑菌率达到86.2%。In order to promote the antibacterial properties of polyvinylpyrrolidone(PVP),the natural bacteriostatic agent aloe was loaded in PVP.PVP/Aloe composite nanofiber membranes with different mass ratios were prepared by electrospinning.The morphology,hydrophilicity(hydrophobicity),particle size and group structure of the composite nanofiber membrane were characterized and analyzed by means of scanning electron microscope,Fourier transform infrared spectroscopy,contact angle analyzer and surface tensiometer.The results showed that due to the physical interaction between aloe and PVP,the prepared nanofibrous membrane showed a fritter-like structure that was separated from each other and adhered to each other.When the mass ratio of PVP and aloe vera was 10∶4,the fritter-like structure formed was the most obvious.The antibacterial experiment shows that the nanofiber membrane has antibacterial effect on Staphylococcus aureus,and the antibacterial rate reaches 86.2%.
