Ultra-long polyaniline nanowires with an average diameter of 60 nm and length up to tens of micrometers were successfully synthesized via chemical oxidation polymerization in an aqueous solution. These nanowires exhibited reversible electrochemical behavior judged from cyclic voltammetry curves. The excellent photosensitivity and photoresponse of a bundle of nanowires were also investigated, which showed that the photocurrent enhanced by ca. 4 times under irradiation of an incandescence lamp (12 V, 10 W). This work might be useful in the fabrication of photosensor and photoswitch nanodevices in the future.
通过水溶液中的化学氧化聚合成功合成了平均直径为60纳米、长度达数十微米的超长聚苯胺纳米线。从循环伏安曲线判断,这些纳米线表现出可逆的电化学行为。还研究了一束纳米线的优异光敏性和光响应,结果表明在白炽灯(12伏,10瓦)照射下光电流增强了约4倍。这项工作未来可能有助于制造光传感器和光开关纳米器件。
