摘要： 导电高聚物作为一种新型材料具有独特的电子、电化学和光学性质, 其中最令人感兴趣的是导电高聚物能受控在导电态和绝缘态之间可逆的转换. 这使得导电高聚物在制备新型微电子器件方面具有潜在的实用价值[ 1], 而该应用又要求导电高聚物可进行选择性的微区聚合.由于激光具有能量集中而且可调谐的特点, 可影响甚至控制电化学反应过程, 而且对加工条件的要求相对简单[ 2], 因而自从Von Gutfeld等首先报道激光诱导电沉积以来[3], 人们在利用激光诱导进行选择性加工方面作了大量的工作[4～7]. 目前利用激光进行材料微加工已成为一重要发展趋势, 但在金属电极表面进行激光诱导电聚合的报道却很少, 至今只有 Haraguchi 等报道了聚苯胺在金电极表面的激光诱导电聚合[8], 并因而开展这方面的工作具有重要的意义.最近, 本实验室利用激光诱导电化学聚合的方法, 对聚吡咯(PPY)和聚邻苯二胺(POPD)进行选择性的微区聚合, 开展了有关电化学微米加工的初步研究。

Abstract: It has been shown that laser can induce selective local electropolymerization of polypyrrole(PPY)and poly-o-phenylenediamine(POPD). The resonance Raman spectroscopic result indicates that the structure of the laser induced PPY is nearly identical to that of the PPY formed under the normal condition of electropolymerization. It seems to be reasonable to assume that the laser induced thermal effect is most likely to influence the electropolymerization kinetics, as the temperature rise at the illuminated surface area results in considerable shift of the equilibrium potential. Electrochemical micro patterns were achieved by laser-induced electropolymerization of PPY and POPD on Au and HOPG electrode. The diameter of points and the width of lines obtained are about 2～4 and 8 micrometers respectively.

Key words: laser-induced, electropolymerization, microfabrication, polypyrrole, poly-o-phenylenediamine
