Investigation of Conducting Poly(3,4-Ethylene Dioxy Thiophene) Film on Surface of Tantalum/Tantalum Pentoxide-Based Anode

This article investigate method of preparation in situ chemistry polymeriztion of conductive polymer poly 3,4-ethylene dioxy thiophene thin film in micropore interior surface of sinter Ta/Ta2O5 anode. The formed mechanism of macromolecule chain in restriction space as well as electrical conductivity of film in micropore interior on weak adherence occasion have been analysed with performance change of organic piece solid tantalum electrolytic capacitor. The analytic results show that, the chain length of macromolecule which polymerizing in restriction space will be changed as a result of affect of restriction energy.
