The approaches,by which conducting polypyrrole could be electrodeposited on the surface of tantalun/tantalum pentoxide-based anode(1 microfarad, 16V), have been studied. The galvanostatically polymerized polypyrrole is used for the cathodes of tantalum electrolytic capacitors. Particularly, the influence of electropolymerization conditions, such assupporting electrolyte solution composition, anodic current value and applied mode, on the capacitance and dissipation factor of as-made capacitor has been discussed.

Also, the effects of the amount of tantalum pentachloride and reaction time on the softening point of the pitch were investigated. Results showed that the tantalum particles were dispersed homogeneously in the pitch precursor with sizes in the range of 20-50nm. The tantalum particles mainly existed in the form of δ-Ta2O5 when the reaction temperature was 420℃. By further heat treatment,δ-Ta2O5 was transformed into β-Ta2O5 at 900℃.Β-Ta2O5 and TaC co-existed at 1200℃. At 2800℃, all the tantalum was transformed into TaC.
