摘要
采用高能球磨法制备了纳米金属粒子/有机物复合材料,运用扫描电镜(SEM)、透射电镜(TEM)和X射线衍射仪对复合材料的微观形貌特征和结构进行了分析研究,并探讨了球磨时间对复合材料微观形貌特征的影响。研究结果表明,经过超声振动后复合颗粒分布较均匀,100h球磨后锌粒的粒径大约为100nm左右,呈层片状分布,聚氯乙烯与锌复合后,均匀地包覆在锌粒的表面。球磨50h、80h、100h和120h铜粒的粒径分别为300nm、140nm、70nm和30nm左右,近似圆球状,石蜡可以完全包覆纳米铜粒子。
The nanometer metal/polymer composite is prepared by high energy ball milling. The microstructures and characterization of nanometer metal/polymer composite are studied by the X-ray diffraction (XRD), the scanning electron microscopy (SEM) and the transmission electron microscopy (TEM). The effect of milling time on the microstructures of nanometer metal/polymer composite are researched. The results show that the diameter of zinc powder is in the range of 1 hundred nanometers in parallel form and is evenly rounded by PVC layer. The diameter of cupper and powder which receives ball milling for 50 h, 80 h, 100 h, and 120 h is about 300 nm, 140 nm, 70 nm, 30 nm respectively in ball form; paraffin can evenly cover copper particles.
