| 摘 要： | 利用原位电化学原子力显微镜(in-situ EC-AFM)研究了纳米氧气气泡在高定向热解石墨(HOPG)表面的电化学控制产生与生长. AFM原位图像表明电化学产生的氧气在HOPG表面形成了纳米气泡, 并且纳米气泡的产生与生长可以通过改变外加电压和反应时间来进行控制. 随后, 研究了电化学产生的纳米氧气气泡对于在HOPG表面电化学聚合吡咯反应的影响, 结果表明伴随聚合反应过程产生的纳米氧气气泡使得生成的聚吡咯膜表面形成了气泡状的缺陷.

| Abstract: | The electrochemically controlled formation and growth of oxygen nanobubbles were observed on bare highly oriented pyrolytic graphite(HOPG) surface via in-situ electrochemical atomic force micros-copy(in-situ EC-AFM).The formation and growth could be well controlled by tuning either the applied voltage or the reaction time.The growth effect of the nanobubbles on pyrrole electropolymerization on the HOPG surface was further studied,demonstrating that the oxygen nanobubbles were responsible for the bubble-shap... |
