反相微乳液制备AgCl/PMMA复合胶乳及其抗菌性能
Preparation of AgCl/PMMA Latex via W/O Microemulsion and its Antibacterial Activity
摘要
Abstract
Composites containing silver halide nanoparticles have attracted great interest as potential antibacterial materials. AgCl nanoparticles were synthesized in W/O microemulsion using octylphenylpolyethylene glycol (OP) as the emulsifier and methyl methacrylate (MMA) as the oil phase. AgCl/PMMA complex latex was prepared via in situ microemulsion polymerization. Effects of surfactant (cOP) and salt (csalt) concentration on the formation and morphology of AgCl nanoparticles were studied by ultraviolet-visible spectrum and transmission electron microscopy (TEM). Furthermore, the antibacterial effect of AgCl/PMMA latex was evaluated againstE. coli. The results show that the AgCl nanoparticles prepared were spherical with a mean diameter of about 5 nm. The increase ofcOPandcsalt promotes the formation of AgCl nanoparticles with smaller diameter in the W/O microemulsion, which provide the AgCl/PMMA latex good antibacterial activity. This simple and mild preparation method can be easily applied in an industrial scale process. Therefore, the AgCl/PMMA latex prepared is a novel antibacterial latex with great potentially applications.关键词
