【摘要】：引入了一种操作简便的制备高固含量银纳米墨水的方法,以月桂酸作为保护剂,水合肼作为还原剂,一步发制备出粒径均匀,尺寸为20nm,且固含量可达14%的银导电墨水。分别探究了硝酸银用量,水合肼含量等因素对产物形貌和固含量的影响。采用冷场发射扫描电子显微镜和紫外可见分光光度计对产物的形貌和尺寸分布进行了测试。最后,银墨水经小于200℃的低温烧结后,获得电阻最低为17mΩ/的银薄膜层,为纳米银墨水在柔性电路中的应用奠定了基础。
[Abstract]:A simple and convenient method for preparing silver nano-ink with high solid content was introduced. Silver conductive ink with uniform particle size of 20 nm and solid content of 14% was prepared in one step with lauric acid as protective agent and hydrazine hydrate as reducing agent. The effects of the amount of silver nitrate and the content of hydrazine hydrate on the morphology and solid content of the product were investigated. The morphology and size distribution of the products were measured by cold field emission scanning electron microscope and UV-Vis spectrophotometer. Finally, the silver film layer with the lowest resistance of 17m 惟 / was obtained after the silver ink was sintered at low temperature below 200 鈩，
