USE OF CONJUGATED OLIGOMER AS ADDITIVE FOR FORMING CONDUCTIVE POLYMERS
A process for forming a capacitor. The process includes providing an anode; providing a dielectric on the anode; exposing the anode to a polymer precursor solution comprising monomer, conjugated oligomer and optionally solvent and polymerizing the polymer precursor. The ratio between monomer and conjugated oligomer ranges from 99.9/0.1 to 75/25 by weight. The solvent content in the polymer precursor solution is from 0 to 99% by weight.
