Silver nanoparticles (AgNP) are being used extensively in medical and modern age stretchable and flexible electronics applications. In this article, we describe easy, cost-effective, and scalable synthesis of AgNP using electrolysis of pure silver metal in aqueous silver acetate solution. Size measurements and structural characterizations of the nanoparticles were performed using scanning electron microscopy coupled with image analysis and X-ray diffraction techniques, respectively. As-prepared nanoparticles were dispersed in pure ethylene glycol (EG) in a concentration of 50 wt%. The dispersion was coated on a soft, sticky, stretchable, and flexible elastomeric substrate polydimethylsiloxane (PDMS). Finally, the stretchability and flexibility tests on AgNP-EG/PDMS laminate were performed. The as-fabricated AgNP-EG/PDMS laminate is capable of stretching up to 18% without electrical failure. It was also found to remain electrically conductive when bent on curved surfaces. This behavior indicates that the AgNp-EG/PDMS laminate has good stretchability and flexibility and can be used as an electrically conductive platform for stretchable and flexible electronics.

AgNP的电化学合成和AgNP-EG涂层在软弹性体上的机械性能

银纳米粒子 (AgNP) 被广泛用于医疗和现代可拉伸和柔性电子应用。在本文中，我们描述了使用纯银金属在醋酸银水溶液中电解的简单、经济且可扩展的 AgNP 合成。使用扫描电子显微镜结合图像分析和 X 射线衍射技术分别进行纳米颗粒的尺寸测量和结构表征。将制备的纳米颗粒以 50 wt% 的浓度分散在纯乙二醇 (EG) 中。将分散体涂覆在柔软、粘性、可拉伸且柔韧的弹性基材聚二甲基硅氧烷 (PDMS) 上。最后，对 AgNP-EG/PDMS 层压板进行了拉伸性和柔韧性测试。制造的 AgNP-EG/PDMS 层压板能够在不发生电气故障的情况下拉伸高达 18%。还发现它在弯曲表面上弯曲时仍保持导电性。这种行为表明 AgNp-EG/PDMS 层压板具有良好的拉伸性和柔韧性，可用作可拉伸和柔性电子产品的导电平台。
