Description
技术领域
本发明涉及一种电容器铝箔上制备PEDT/PSS导电膜的电沉积方法。
背景技术
目前，虽然PEDT/PSS的水溶液已经广泛应用于固态电容器的生产制造，但其应用方式基本都是采用简单含浸，既通过含浸使PEDT/PSS附着在电容器的阴阳极箔和电解纸上，这种方式存在以下问题，铝箔的微小孔隙难以填充，PEDT/PSS导电膜与铝箔结合不紧密，这会导致电容引出率不高的同时，电容经过后续的组立、高温老练等工序后PEDT/PSS导电膜容易从铝箔上脱落，影响电容的性能。在铝电解电容器中常常在铝箔上沉积一层导电膜，然而现有的导电膜与铝基体结合不紧密造成固态电容器产品的性能不稳定，同时也使得电容器的电容引出率不高。
发明内容
本发明要解决的技术问题是克服现有技术的不足，提供一种与铝基体结合紧密，导电性好的电容器铝箔上制备PEDT/PSS导电膜的电沉积方法。
为解决上述技术问题，本发明提出的技术方案为：一种电容器铝箔上制备PEDT/PSS导电膜的电沉积方法，包括阳极棒、阴极棒和电解液；所述阳极棒为表面平整的铝电极、经化学或电化学腐蚀后的多孔铝电极或者表面具有氧化膜的化成铝箔并且氧化膜上预制有一层导电层；所述阴极箔为石墨或者金属片；所述电解液为PEDT/PSS的水溶液。
上述的电容器铝箔上制备PEDT/PSS导电膜的电沉积方法，优选的，所述PEDT/PSS的水溶液的浓度为0.1～30wt%。
上述的电容器铝箔上制备PEDT/PSS导电膜的电沉积方法，优选的，在所述电解液中加入0.1～50%vol%的添加剂，所述添加剂包括甲醇、乙醇、乙二醇、二甲基亚砜或氢氟烷中的一种或者多种。
上述的电容器铝箔上制备PEDT/PSS导电膜的电沉积方法，优选的，所述阳极棒和阴极棒之间直流的电流密度值取值范围为0.1～10mA/cm2，电沉积时间为1～60min，溶液温度为室温～90℃。
与现有技术相比，本发明的优点在于：在外加电场作用下，PEDT/PSS溶液 中的PSS—离子会引导PEDT/PSS迁移至电解液/铝界面，从而使得PEDT/PSS逐渐在铝箔上沉积析出，所以采用本发明的方法可使得PEDT/PSS与铝基体即阳极棒结合更紧密，也有利于导电高分子材料更好的填充腐蚀铝箔的孔隙，既可以提高电容的引出率，也可以保证固态电容产品性能的稳定性。
