Electrically conductive polypyrrole(PPy)-poly(N-methylpyrrole) (PNM P) composites were prepared by electrochemical polymerization of the corresponding monomers at a platinum electrode surface in 0.036M sodium dodecylsulfate(NaDS)/distilled water(H2O) electrolyte solution system. Two types of composites were prepared and characterized by TGA, SEM, and 4-probe meter.
