Reaction Steps

Pentaerythrityl tetrasulfate ammonium salt is prepared from pentaerythritol and sulfamic acid in N,N,-dimethylformamide. A mixture of 5 grams of pyrrole and 5 grams of the ammonium salt in 200 ml. water is prepared and electropolymerized in a 8×7×4.5 cm reaction vessel wherein the cathode is a 15×5×0.025 cm nickel sheet. About 40 cm2 of the nickel sheet is immersed in the bath. The distance between electrodes is 4.5 centimeters. Electropolymerization is conducted at a current of 0.3 amperes for a period of 10 minutes yielding a black electronically conducting film characterized by a somewhat rough surface on the solution side of the film.
