摘　　要：从仿生的观点出发,选择具有分形结构的叉枝藻(海藻的一种)作为基底材料,经预处理后用化学沉积方法,先在海藻基底上沉积得到一层铜金属,之后再用电沉积方法,使基底表面的金属铜层加厚到一定程度(30～50μm),最后通过烧蚀去除包裹在铜金属中的海藻,从而得到较为纯净的具有分形结构的金属材料。采用计盒维数法计算出该金属材料的分维数(在准二维上)为1.59。A way of manufacturing metallic (Cu) material with fractal structure was studied using the biomimetics and fractal concept.Some algae with natural fractal structure were used as the basis foundations.Metal (Ca) was coated on the foundations by electroless deposition and electrodeposition.After elimination of the founda-tional algae by erosion,dissolution etc,a pure metallic (Cu) material with fractal structure was obtained.The fractal dimension (FD) of the metal material was calculated to be 1.59 by means of box-counting technique.
