Polyacrylamide-metal (M = Pt, Ag, Cu) nanocomposites with metal nanoparticles homogeneously dispersed in the polymer matrix have been successfully prepared with the corresponding metal salt and acrylamide monomer in ethylene glycol by microwave heating. This method is based on the single-step simultaneous formation of metal nanoparticles and polymerization of the acrylamide monomer, leading to a homogeneous distribution of metal nanoparticles in the polyacrylamide matrix. Ethylene glycol acts as both a reducing reagent and a solvent, thus no additional reductant is needed. Another advantage is that no initiator for AM polymerization and no surfactant for stabilization of metal nanoparticles are necessary. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), ultraviolet visible (UV-vis) absorption spectra, and thermogravimetric (TG) and differential scanning calorimetric analysis (DSC).
通过微波加热，在乙二醇中用相应的金属盐和丙烯酰胺单体成功制备了金属纳米颗粒均匀分散在聚合物基质中的聚丙烯酰胺-金属（M = Pt、Ag、Cu）纳米复合材料。该方法基于金属纳米颗粒的单步同时形成和丙烯酰胺单体的聚合，导致金属纳米颗粒在聚丙烯酰胺基质中均匀分布。乙二醇既是还原剂又是溶剂，因此无需额外的还原剂。另一个优点是不需要用于丙烯酰胺聚合的引发剂，也不需要用于稳定金属纳米颗粒的表面活性剂。通过X射线粉末衍射（XRD）、透射电子显微镜（TEM）、傅里叶变换红外（FTIR）、紫外可见（UV-vis）吸收光谱以及热重（TG）和差示扫描量热分析（DSC）对产物进行了表征。
