Synthesis and characterization of conducting polypyrrole and multi-walled carbon nanotubes co-depositing onto nickel electrodes

This paper presents synthesis and characterization of conducting polypyrrole-multi-walled carbon nanotube films co-depositing onto nickel electrode substrate. The electrochemical polymerization of pyrrole is performed in 100ml aqueous solution containing 0.2M pyrrole, 0.05M AOT and 0.01g multiwalled carbon nanotubes using three-electrode system. The SEM and cyclic voltammetry analysis show that the incorporation of multiwalled carbon nanotubes into polypyrrole enhance the conductivity and electrochemical behavior of composites films.
