Abstract

Due to the remarkable electrical conductivity and superior mechanical properties of carbon nanotubes (CNTs), as well as the rich optical, electronic and electrochemical properties of conducting polymers, nanocomposites of conducting polymers and CNTs have been pursued with an aim to synergistically combine their individual components. We demonstrate for the first time the use of single stranded DNA wrapped single walled carbon nanotubes (ss-DNA/SWNTs) to in-situ fabricate a water-soluble nanocomposite of self-doped polyaniline/SWNTs. Due to their unique surface and electronic properties, the ss-DNA/SWNTs performed multiple roles in the greatly enhanced performance of the self-doped polyaniline [poly(aniline boronic acid) (PABA)in this work] both during and after the polymerization, which makes this work unique compared to previously reported conducting polymer/carbon nanotube composites[1,2].
