Abstract:

通过直流电弧等离子法制备纳米铜粉,利用X射线衍射(XRD)、X射线荧光分析(XRF)、透射电子显微镜(TEM)和相应的选区电子衍射(SAED)等测试手段对样品的晶体结构、成分、形貌和粒径分布进行表征,测试纳米Cu粉在无水乙醇介质中pH-Zeta电位图,系统研究了超声时间、不同表面活性剂及其加入量对纳米铜粉在无水乙醇介质中分散稳定性的影响,并对其分散机理进行了探讨。结果表明直流电弧等离子法制备的纳米铜粉纯度高达99.91%(质量分数,下同),粒径分布窄,分散性好,颗粒呈链球型,多晶立方结构。在无水乙醇介质中,推荐较好的纳米Cu粉分散稳定性工艺采用油酸(OA)/十二羟基硬脂酸(HSA)复合表面活性剂修饰,其加入量为OA-0.5%,HSA-0.5%,超声70min,pH值为9。
