采用表面电化学聚合方法，发展了一种无模板法制备大面积长度可控且取向良好的聚吡咯纳米线阵列的方法。纳米线的直径在80 ~ 100 nm之间，长度在1-4 μm之间。此外，证明了相应的增强的聚吡咯纳米线阵列的电化学性能。纳米线阵列表现出566 F g−1的显着电容，并且在数百次充放电循环后保持其初始电容的70%，几乎没有衰减，这比无序纳米线网络和传统薄膜要好得多。
A template-free approach to fabricate a large area of length-controllable and well-oriented polypyrrole nanowire arrays is developed by using a facial electrochemical polymerization strategy. The diameters of the nanowires range from 80 to 100 nm, and their length can be controlled within the range 1–4 μm. Further, the corresponding enhanced electrochemical performance of polypyrrole nanowire arrays is demonstrated. The nanowire arrays exhibited a remarkable capacitance of 566 F g−1 and retained 70% of its initial capacitance with little fading after hundreds of charge–discharge cycles, which are much better than disordered nanowire networks and conventional film.
