摘要:
采用熔融共混的方法,在密炼机上制备了聚乳酸/纳米银负载二氧化硅(PLA/Ag-SiO2)纳米复合材料,并通过透射电镜、抑菌率和动态力学分析仪表征了复合材料的微观形态结构、抗菌性能和动态力学性能。研究结果表明,Ag-SiO2颗粒均匀地分散在在聚乳酸基体中,对金黄色葡萄球菌和大肠杆菌均体现出良好的抗菌作用,而纳米复合材料的储能模量尽管随着纳米粒子含量的增加而增加,但在纳米粒子含量低于10 000 ppm时,纳米复合材料的储能模量均低于纯聚乳酸。
Abstract:
Antimicrobial poly(lactic acid)(PLA)/nanosilver-loaded silica(Ag-SiO2)nanocomposites were prepared by melt compounding on an internal mixer. Morphology, amtimicrobial property and dynamical mechanical properties of the nanocomposites were investigated in terms of transmission electron microscope(TEM), bacteria-inhibiting rate and dynamical mechanical analysis, respectively. It showed that the Ag-SiO2 nanoparticles disperse homogeneously in the PLA matrix, and display potent antibacterial action against S. aureus and E. coli. Although the storage modulus of nanocomposites increased with the increasing Ag-SiO2 particals contents, it is lower than that of the pure PLA in the case of nanoparticles loading level below 10 000 ppm.
