In this study, an underwater impulse discharge initiated in an aqueous suspension of a polylactide acid between silver rods is applied to produce silver nanoparticles (AgNPs) and create a polymer nanocomposite. The spectral and energy characteristics of the discharge are obtained. The composites are characterized by methods of scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, and thermogravimetric analysis. Investigation of the formation of the composite of polylactic acid (PLA) with AgNP has been performed using the molecular dynamics method. The PLA/AgNPs composite films were effective against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Candida albicans, and thus may find future application in the food packaging area.

等离子体在液体中制备的具有抗菌活性的聚乳酸/银-NP纳米复合材料的实验和计算研究

在这项研究中，在银棒之间的聚丙交酯酸的水悬浮液中引发的水下脉冲放电被用于产生银纳米颗粒（AgNP）并产生聚合物纳米复合材料。获得了放电的光谱和能量特征。通过扫描电子显微镜，透射电子显微镜，红外光谱和热重分析的方法来表征复合材料。已经使用分子动力学方法研究了具有AgNP的聚乳酸（PLA）复合物的形成。PLA / AgNPs复合膜对大肠杆菌，金黄色葡萄球菌，枯草芽孢杆菌，白色念珠菌均有效。，因此可能会在食品包装领域中找到未来的应用。
