摘要本文研究了含聚乙二醇（Polyethylene glycol，PEG）电解液中多孔阳极氧化铝（Porous anodic alumina，PAA）模板的制备。在含有 PEG 的草酸、磷酸二氢铵电解液 中通过二次氧化法、高场阳极氧化法制备 PAA 模板，并对 PAA 模板进行了通孔处理。通 过分析所得阳极氧化曲线研究不同溶液中 PAA 模板的制备过程；使用扫描电子显微镜（Scanning electron microscopy，SEM）表征 PAA 膜的形貌、孔间距等特征。 通过实验发现，含 PEG 溶液中 PAA 模板阳极氧化规律与传统水溶液中相似。无论在草酸溶液或者磷酸二氢铵溶液中，PEG 作为调节剂加入均能很好地提高电解液的耐温性和 耐压性，使 PAA 模板能够在更高的电压下制备，减小了击穿的风险，为快速制备大孔间 距 PAA 模板提供了新途径。76002

Title Study on the preparation of PAA templates in the electrolyte containing PEG

Abstract In this work, the preparation of porous anodic alumina (PAA) templates in the electrolyte containing polyethylene glycol (PEG) was researched。 PAA templates were fabricated by two-step constant voltage anodization and high-field anodization in the oxalic acid and ammonium dihydrogen phosphate electrolyte containing PEG, and then through-hole membranes of porous alumina were successfully fabricated。 The preparation of PAA templates were studied by analyzing the curve of anodic oxidation。 PAA templates’ morphology, pore size and other characteristics were characterized by scanning electron microscopy(SEM)。 As can be seen from the experiments, the law of PAA templates’ anodization in PEG-containing electrolyte is similar to that in aqueous solution。 Both in oxalic acid and ammonium dihydrogen phosphate electrolyte, PEG can effectively improve electrolyte’s temperature resistance and voltage resistance as a modifier。 It can enable PAA templates to be prepared at higher voltages, reduce the risk of breakdown, make it possible for the rapid preparation of large hole spacing PAA templates。
