摘要:
采用水合肼还原法制备抗氧化Cu粉,并研究还原剂用量、分散剂用量、抗氧化剂用量和反应温度等因素对纳米Cu粉粒径及表面抗氧化性能的影响。通过X线衍射仪(XRD)、X线荧光分析仪(XRF)、透射电子显微镜(TEM)等表征方法,研究Cu粉的晶体结构、纯度以及形貌。纳米Cu粉的最佳制备工艺为:n(N2H4·H2O)/n(CuSO4)=5,温度为50 ℃,苯骈三氮唑的含量为8%,聚乙烯吡咯烷酮的含量为10%。制备的Cu粉的纯度高达99.91%,平均晶粒粒径为80 nm,粒径分布均匀。
Abstract:
Anti-oxidation copper powders were prepared by N2H4·H2O reduction method. The optimal conditions to prepare the copper nanopowders were obtained by studying the effects of following factors,such as the reducing agent,the dispersing agent,antioxidant and the temperature on the particle size and oxidation resistance of copper powders.The properties, such as microstructure,purity and morphology of copper powders were analyzed by X-ray diffraction(XRD),X-ray fluorescence(XRF), transmission electron microscope(TEM).The optimization conditions were as follows:the molar ratio of N2H4·H2O and CuSO4 of 5,temperature of 50 ℃,8% benzotriazole(BTA), and 10% polyvinylpyrrolidone(PVP)as disperser.The well-dispersed uniform copper powders with a high purity of 99.91% were synthesized under optimized conditions,its mean diameter was 80 nm.
