用聚乙烯醇(PVA)作为还原剂和封端剂合成稳定的银纳米粒子，采用立体稳定法将银纳米粒子掺入聚合物基体中。用紫外?可见光谱、透射电子显微镜和傅里叶变换红外光谱等手段表征掺入聚合物基体中的银纳米粒子。紫外?可见光谱结果表明合成的银纳米粒子的特征峰为426 nm，透射电子显微镜表明银纳米粒子为球形，尺寸为10~13 nm，接着用紫外光照射还原，然后采用紫外?可见光谱分析其催化性能。结果表明，合成的银纳米粒子在亚甲基蓝还原中具有良好的催化性能。
Stable silver nanoparticles were synthesized using polyvinyl alcohol (PVA) as reducing and capping agent. The method of steric stabilizationwas adopted for the incorporation of silver nanoparticles in the polymer matrix. The successful incorporation of silver nanoparticles in a PVA matrix was confirmed by UV–Visiblespectroscopy, transmission electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectroscopy. The synthesizedsilver nanoparticleswere characterized by a peak at 426 nm in the UV–Vis spectrum. TEM studies showed the formation of spherical shaped silver nanoparticles of 10?13 nm, following the reduction by UV irradiation. Catalytic properties were studied by means of UV-Visiblespectroscopic analysis.The synthesized silver nanoparticles exhibited good catalytic properties in the reduction of methylene blue.
