通过多巴胺氧化物聚合和聚多巴胺（PDA）在纤维硅酸盐表面自组装制备表面改性纤维硅酸盐（FS），通过将聚多巴胺-PDA简单浸在银纳米粒子溶液中，预合成的银纳米粒子粘附在表面改性纤维硅酸盐（FS-PDA）表面，这是由于表面的PDA涂层具有儿茶酚和含氮基团的金属结合能力。用x射线光电子能谱法测定了改性FS表面的化学成分。透射电镜观察了FS纳米纤维的表面形态变化。结果表明，多巴胺在FS表面的原位自发氧化聚合和Ag纳米颗粒在FS表面的固定化是成功的。以大肠杆菌为模型菌株制备的FS- pda /Ag与原始FS相比，抗菌性能显著增强。©2013 Wiley期刊公司j:。变异较大。自然科学学报，2014,31(1):39859。
Surface modified fibrillar silicate (FS) was prepared by dopamine oxide polymerization and self-assembly of poly(dopamine) (PDA) on the FS surface, presynthesized silver nanoparticles subsequently adhered to the PDA functionalized FS (FS-PDA) surface by simply dipping FS-PDA in silver nanoparticles solution, owing to the metal-binding ability of catechol and nitrogen-containing groups on the PDA coating on the surface of FS. The chemical composition of the modified FS surface was determined by X-ray photoelectron spectroscopy. Surface morphological changes of the FS nanofibers were observed by transmission electron microscopy. The results indicated that the in situ spontaneous oxidative polymerization of dopamine on the FS surface and the immobilization of Ag nanoparticles on the surface of FS were successful. The FS-PDA/Ag demonstrated a significant enhancement in antibacterial properties compared to the pristine FS by using Escherichia coli as model strain. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
