本文报道了用静电纺丝法制备的芦荟衍生纤维的抗菌效果。制备了不同浓度的芦荟聚乙烯吡咯烷酮（Av/PVP）和芦荟醋酸盐-聚乙烯吡咯烷酮（AvAc/PVP）电纺纤维，并对其微观结构和力学性能进行了研究。采用差示扫描量热法（DSC）、热重分析（TGA）、水接触角（CA）、傅里叶变换核磁共振（FT-NMR）、扫描电镜（SEM）、X射线衍射（XRD）、CHNSO和傅里叶变换红外光谱（FT-IR）等方法对制备的样品进行了表征。(Av/PVP）电纺纤维用不同浓度（6-10重量%）的PVP和0.2重量%的Av共混制备，并在草药中测试伤口愈合、抗菌和抗炎性质。为了进一步研究，研究了AvAc膜对复合膜性能的影响。AvAc提高了样品的热稳定性和微晶尺寸百分比。对支架的抗菌和抗病毒试验研究显示没有细菌和病毒生长。这些结果表明，AvAc/PVP支架可能是用于伤口愈合应用的有希望的候选者。
In this work, the anti-bacterial effect of Aloe vera derivate fibers produced by the electrospinning method was reported. Aloe vera Polyvinylpyrrolidone (Av/PVP) and Aloe vera acetate-Polyvinylpyrrolidone (AvAc/PVP) electrospun fibers were prepared with different concentrations and their microstructure and mechanical properties were studied. Various methods such as differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), water contact angle (CA) tests, Fourier-Transform Nuclear Magnetic Resonance (FT-NMR), scanning electron microscope (SEM), X-ray diffraction (XRD), CHNSO and Fourier-Transform Infrared Spectroscopy (FT-IR) were used to characterize prepared samples. (Av/PVP) electrospun fibers were prepared with different concentrations (6-10 wt%) of PVP and 0.2 wt% Av blended and tested in medicinal herb for wound healing, antibacterial and anti-inflammatory properties. For further study, the effect of AvAc film on the properties of composite film was studied. AvAc increased the thermal stability and crystallite size percentage of samples. Antibacterial and antiviral test studies on the scaffold displayed no bacterial and viral growth. These results suggest that AvAc/PVP scaffolds could be promising candidates for wound healing applications.
