| 摘 要： | 首先以金属凝胶纤维为模板,通过自由基聚合制备了聚N,N'-亚甲基双丙烯酰胺(PMBA)一维纳米结构,然后以还原剂处理聚合产物,使金属凝胶中的银离子(Ag+)还原成单质银(Ag),得到了负载银纳米颗粒(Ag NPs)的聚合物一维纳米结构。采用透射电子显微镜(TEM)比较了不同还原方法对还原产物微观形貌的影响,借助X射线能谱分析(EDX)和衍射图证实了银的存在。所得到的负载Ag NPs的聚合物一维纳米结构可用于催化亚甲基蓝降解。

| Abstract: | Using metallogel fibers as templates, poly(N,N'-methylene bisacrylamide) (PMBA) one-dimensional (1D) nanostructures were fabricated via radical polymerization, and subsequently, polymerized products were treated using the reducing agent instead of removal of the template. Silver nanoparticles (Ag NPs) loaded polymer 1D nanostructures could be produced through the reduction of silver ions (Ag+) to elemental Ag. The microscopic morphology of the reduction products obtained by different reduction methods were characterized by Transmission Electron Microscopy (TEM). The Electron-Dispersive X-ray(EDX) spectrometry and electron diffraction image confirmed the existence of silver in the product. The as-prepared Ag NPs loaded polymer 1D nanostructures could be used to catalyze the degradation of methylene blue. |
