摘要: 应用电化学恒电位法结合模板法制备聚苯胺纳米点阵列,导电原子力显微镜研究处于不同氧化还原态的聚苯胺纳米点的I~V特性,发现只有处于部分氧化态(导电态)的聚苯胺纳米点才出现库仑台阶效应,还原和全氧化态聚苯胺纳米点不显示库仑台阶.初步探讨了上述现象.

关键词: 聚苯胺纳米点, 氧化还原态, 库仑台阶效应

Abstract: Polyaniline nanodot array had been fabricated in AAO template with potentiostatic method and the I~V characteristics of nanodots with different redox states were measured by conducting atomic force microscope (C-AFM) in atmosphere at room temperature. We found that only nanodots in partial oxidation state exhibit coulomb staircase in the I~V curves,while those in the full oxidation state and reduced state do not. The above phenomena were discussed preliminarily.

Key words: PANI nanodot, redox state, Coulomb staircase effect
