银和铜纳米线已使用可扩展的交流电沉积方法合成到多孔氧化铝模板中，可产生约克数量的金属纳米线。 Ag 和 Cu 的直径分别为 25 nm，长度分别为 5 和 10 μm。纳米线已用于通过溶液加工制备聚苯乙烯纳米复合材料。对含有不同体积分数的金属的聚合物纳米复合材料进行的电阻率测量表明，在0.25和0.75体积％的组合物之间获得了纳米线的低渗透阈值。
Silver and copper nanowires have been synthesized using a scalable method of AC electrodeposition into porous aluminum oxide templates, which produces gram quantities of metal nanowires ca. 25 nm in diameter and up to 5 and 10 mu m in length for Ag and Cu, respectively. The nanowires have been used to prepare polystyrene nanocomposites by solution processing. Electrical resistivity measurements performed on polymer nanocomposites containing different volume fractions of metal indicate that low percolation thresholds of nanowires are attained between compositions of 0.25 and 0.75 vol %.
