Paper Abstract

We report studies of the electropolymerized polypyrrole (PPy) films around vertically aligned bamboo-like multiwall carbon nanotube (MWNT) arrays. Raman spectroscopy has revealed large percentage dipolarons resulting from highly conjugated PPy. The expected high conductivity of PPy-MWNT composite has also demonstrated by electrochemical studies. The SEM and TEM microscopy observations of the high mechanical strength, dense packing and strong adhesion exhibited in this composite are results of the π-stacking between the PPy backbone and the aromatic MWNT sidewalls.
