采用高压放电的方式对材料进行击穿, 可以方便地制造纳米颗粒.搭建了高压击穿实验装置, 对铜丝进行高压击穿实验;分别采用透射电子显微镜(TEM)、扫描电子显微镜( SEM )和元素能谱(EDS)、X射线衍射( XRD) 测试, 对铜丝击穿丝状物进行了形貌和成份分析.研究了铜丝高压击穿后的物相特性.研究结果发现, 在高压作用下铜丝被充分电离, 产生丝状分布, 其构成为纳米颗粒的凝结;纳米颗粒的直径分布主要集中在30—60 nm之间; 颗粒产物由铜元素和氧元素组成; 它们以单晶Cu, Cu2O和CuO组成混合物;粒径大小、 产物成分与铜丝长度、直径及电压等因素相关.Copper nanoparticles are produced by high-voltage electrical explosion of copper wires. The high-voltage breakdown experimental setup for copper is built. The morphology and composition of the breakdown material are tested by the transmission electron microscopy (TEM) and scanning electron microscopy (SEM), and X-ray diffractometry (XRD) and energy dispersive spectroscopy(EDS) methods, respectively. Based on the morphology, size distribution, elemental spectrum (EDS), and XRD analysis of the breakdown material, the phase characteristics of high-voltage breakdown copper wire are studied. The results show that wire is fully ionized under high pressure, forming a filamentous distribution which is composed of condensation of nanoparticles. The diameters of copper nanoparticles are between 30 nm and 60 nm. The nanoparticles product is composed of Cu and O elements. The product is a mixture of metallic copper, cupric oxide and cuprous oxide. The particle size and its product composition are controlled by varying length and diameter of the copper wire, discharge voltage, etc.
