摘要
采用去合金化法对Cu0.3Mn0.7合金进行自腐蚀制备出厚度为1mm的纳米多孔铜块体材料。采用XRD、SEM、EDS、AAS等分析了样品的相组成、微观形貌和元素含量。结果表明:样品在室温0.1mol/L盐酸溶液中自腐蚀10d,得到成分单一,结构均匀的三维连通纳米多孔铜块体材料,其表面平均孔径尺寸约125nm,平均骨架尺寸约80nm,横截面平均孔径尺寸约300nm。
A bulk nanoporous copper with thickness of 1 mm was fabricated from freely corroded Cu0.3Mn0.7 alloy by means of dealloying. The phases and microstructure of samples were analyzed by XRD, FESEM, EDS and AAS. The results indicate the nanoporous copper with a uniform monolithic structure in three-dimension can be created by free-corrosion dealloying Cu0.3Mn0.7 alloy in 0.1 mol/L HCl solution for 10 d, with an average surface pore diameter of 125 nm and an average ligament section pore diameter of 300 nm.
