The antibacterial behavior of polypyrrole (PPy) depends on a diversity of structural parameters such as surface area, aggregation level and additives (metal nanoparticles) incorporation. This paper summarizes the influence of different preparation procedures of PPy on action of resulting antibacterial composite against Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae. The bactericidal action has been assigned to morphology (size of polypyrrole nanoparticles). The electrostatic interaction established between polymer nanoparticles and bacteria provokes the bacterial cell death and returns advantages in comparison with conventional composites of polypyrrole decorated with metal nanoparticles.
聚吡咯(PPy)的抗菌行为取决于多种结构参数,如表面积、聚集程度和添加剂(金属纳米颗粒)的掺入。本文总结了聚吡咯不同制备工艺对所得抗菌复合材料针对大肠杆菌、金黄色葡萄球菌和肺炎克雷伯菌的作用的影响。杀菌作用归因于形态(聚吡咯纳米颗粒的尺寸)。聚合物纳米颗粒与细菌之间建立的静电相互作用引发细菌细胞死亡,与用金属纳米颗粒修饰的传统聚吡咯复合材料相比具有优势。
