Description
技术领域
本发明属于电容器生产设备技术领域，具体涉及固态铝电解电容。
背景技术
目前，作为电子***的重要组件，铝电解电容器由于其优良的稳定性逐渐代替电解液电容器或有机半导体电容器，在太阳能、风能新能源中应用。而传统固态电容器的导电聚合物多采用单一的3,4-乙撑二氧噻吩在铁盐氧化剂的作用下聚合生成PEDOT聚合物作为固态电解质，在超过30V电压下固态电容特性发生激变不稳定，容易短路。同时由于固态电解质化成过程容易使得电容阻抗过高，从而使得ESR值升高，限制固态电容器的应用范围，并给其生产成本带来负面影响。
发明内容
发明目的：针对上述现有存在的问题和不足，本发明的目的是提供一种耐高压固态电解电容器。
技术方案：为了解决上述技术问题，本发明采用以下技术方案：一种耐高压固态电解电容器，所述固态电解电容器包含的导电高分子材料的制备方法如下：
将单体一3,4-乙烯二氧噻吩和单体二[3,4]-乙烯-磺酸氨基噻吩加入分子量为20000～40000的聚苯乙烯磺酸的正丁醇溶液中，搅拌形成透明均一的单体溶液，然后加入甲苯磺酸铈得到导电高分子分散液；
将电容芯子进入所述导电高分子分散液，然后在20～45℃下浸润10～60s，并在30～70℃下干燥，得到所述固态铝电解电容器。
作为优选，所述单体一和单体二的质量比例为1～2:1。
有益效果：与现有技术相比，本发明通过两组单体的交联聚合，并以甲苯磺酸铈作为氧化剂聚合生成固态导电高分子，其击穿电压可达220V。
具体实施方式
下面结合具体实施例，进一步阐明本发明，应理解这些实施例仅用于说明本发明而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落于本申请所附权利要求所限定的范围。
