Electroactive composites made of polyaniline and MWCNT modified by aminobenzene groups were electrochemically synthesized. SEM observation confirms that the composites become more porous as the MWCNT aggregation on the electrode surface gradually increases. Paraboloid dependence of specific electrical conductivity on the MWCNT content was found for the composites with more than 2.0 wt % of MWCNT. Obtained results confirmed a strong relationship between the surface and electrical properties allowing to offer their optimization using different amount of MWCNTs and preparation procedure.
