Silver nanoparticles (Ag NPs) coated by an aqueous emulsion of copolymer were elaborated in a short time using polyol process and microwave (MW) heating. This approach is based on reducing AgNO₃ powder in the presence of two main components; ethylene glycol as a dispersed medium and an industrial copolymer (latex) as protecting agent. The structural, morphological and optical properties of the prepared silver nanoparticles have been investigated by UV–Vis spectroscopy, Infrared Spectroscopy (IR), X Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). It was found that all these properties are strongly correlated to the latex copolymer concentration and the MW heating process. The absorption band was determined by UV Visible spectra, showing several bands (localized surface Plasmon band) in the visible region at wavelengths between 410 and 430 nm. The TEM analysis of the obtained products indicates the presence of straight nanowires and dispersed, spherical silver nanoparticles with well-controlled size ranging from 7 to 20 nm. The X Ray Diffraction showed that silver nanoparticles synthesized exhibit face centered cubic (fcc) structure. The infrared spectra show the strong coordination between the surface of silver particles and molecules of latex by O–H and C=O groups. Antimicrobial activity of latex/Ag NPs against E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa has been also demonstrated. The results indicated that latex/AgNPs may damage the structure of bacterial cell membrane.

使用多元醇工艺和微波（MW）加热在短时间内精制了由共聚物的水乳液涂覆的银纳米颗粒（Ag NPs）。该方法基于还原AgNO ₃存在两个主要成分的粉末；乙二醇作为分散介质，工业共聚物（胶乳）作为保护剂。制备的银纳米颗粒的结构，形态和光学性质已经通过紫外可见光谱，红外光谱（IR），X射线衍射（XRD）和透射电子显微镜（TEM）进行了研究。发现所有这些性质与胶乳共聚物浓度和MW加热过程密切相关。通过紫外可见光谱确定吸收带，在410至430nm之间的波长下在可见光区域中显示出几个带（局部表面等离激元带）。所得产品的TEM分析表明存在直的纳米线并且分散，球形银纳米粒子，尺寸受控范围从7到20 nm。X射线衍射表明，合成的银纳米颗粒表现出面心立方（fcc）结构。红外光谱显示，OH和C = O基团在银颗粒表面和乳胶分子之间具有很强的配位作用。乳胶/银纳米粒对细菌的抗菌活性还证明了大肠杆菌，金黄色葡萄球菌和铜绿假单胞菌。结果表明，乳胶/ AgNPs可能破坏细菌细胞膜的结构。
