【摘要】 <正>导电高分子型铝固体电解电容器可以防止电解液的泄漏和干涸,具有可靠性高,工作寿命长和极易片式化的特点。另外,导电高分子的电导率较高,从而可以大大改善电解电容器的高频特性,满足电子线路表面组装和高频化发展的要求,有着广阔的应用前景。导电高分子型电解电容器制备的关键是在被膜过程中,导电高分子能够以较高的电导率, 均匀致密地被覆在微孔内部的表面上,达到提高电容器性能的目的。聚苯胺是一种较为常见更多还原

【Abstract】 Polyaniline were prepared by chemical polymerization in 25v/10μF aluminum electrolytic capacitors. Influence of concentration of aniline to capacitance of capacitors and kinds of electrolyte used for repairing alumina film of capacitors were researched. Results show that concentration of aniline has great effect on capacitance of aluminum solid electrolytic capacitors. At 6mol/L of aniline, capacitance of capacitors reaches its specified capacitance. Ammonium borate is a better electrolyte for repairing alumina film, and can improve performance of aluminum solid electrolytic capacitors.更多还原
