Abstract
An improved electrolytic capacitor, and method of making the electrolytic capacitor, is provided. The electrolytic capacitor comprises an anode comprising a dielectric layer on the anode. A primary conductive polymer layer is on dielectric and a mordant layer on the primary conductive layer wherein the mordant layer comprises a mordant compound of Formula A; wherein:each of R-Ris independently selected from H and —PO(OR)wherein each Ris independently selected from H, substituted or unsubstituted alkyl of 1-20 carbons, substituted or unsubstituted aryl of 6-20 carbons or an alkylaryl of 7-21 carbons; with the proviso that at least one of R-Ris —PO(OH). A secondary conductive polymer layer is on the mordant layer.
