摘要本文通过对未处理、化学抛光和电化学抛光的铝片在不同的电解液中进行一次恒压氧化和二次恒压氧化，制备大孔间距阳极氧化铝（Porous-type Anodic Alumina，PAA)模板。然后再通过酸腐蚀法去除阻挡层。并通过脉冲沉积法和循环伏安（CV）聚合法在PAA模板孔洞中沉积镍并聚合聚苯胺（Polyaniline，PANI）。78110
在阳极氧化的过程中，对不同电解液下形成的氧化铝膜进行比较分析，得出通过乙二醇与磷酸二氢铵反应得到的磷酸酯电解液中效果最佳，在此电解液体系中，氧化电压可调范围大（200 V-400 V），电解液浓度可调范围广（5 wt%-20 wt %)，生长速率快（1。7 μm/min以上），在常温下即可快速得到大孔间距的多孔氧化铝模板且规整性较好。并可以在多孔氧化铝模板上制备PANI纳米结构，通过SEM和电化学测试均可检测出PANI成功地沉积在了PAA孔洞中。

Title Fabrication of nano-structure PANI based on the PAA template
Abstract In this paper, Porous-type Anodic Alumina (PAA) templates were successfully fabricated by one-step and two-step constant voltage anodization methods in different electrolytes on raw materials, chemical polished and electrochemical polished samples。 Then, barrier layer was removed by acid etching。 At last, nickel and polyaniline (PANI) were deposited into PAA templates through the method of pulse electrodeposition and cyclic voltammetry (CV), respectively。
In the process of anodizing, the alumina films fabricated in the electrolyte which is reacted by rthylene glycol and diammonium hydrogen phosphate perform better compared with that in other electrolytes。 This electrolyte present tunable anodization voltage ranging from 200 V to 400 V, concentration ranging from 5 wt% to 20 wt% and has rapid growth rate which is at least 1。7 μm/min。 So it is easy to fabricate the PAA templates in the room temperature in short time and the templates have high regularity。 Nickel and polyaniline nano structures can also be fabricated on that films and the successfully deposition into the nano pores can be analyzed by the image of SEM and CV curves。
