ABSTRACTNanoporous composite films of multi-walled carbon nanotubes (MWNTs) and either polypyrrole (PPy) or poly(3-methylthiophene) (P3MeT) were grown using an electrochemical polymerization technique in which the nanotubes and conducting polymer were deposited simultaneously. The concentration and dispersion of MWNTs in the polymerization electrolyte was found to have a significant effect on the thickness of polymer coated on each MWNT and hence the loading of MWNTs in the films produced. It has been shown that for an increasing concentration of MWNTs in the polymerization electrolyte, the thickness of polymer coated on each MWNT decreases. This relationship made it possible to minimize ionic diffusion distances within the nanoporous MWNT-PPy films produced, reducing their electrical and ionic resistance and increasing their capacitance relative to similarly prepared pure PPy films.

AbstractIn the present study, we have studied photoelectrochemical properties of poly(3-octathiophene) (P3OT), blending with multi-wall carbon nanotubes (MWCNTs). P3OT blended with MWCNTs was characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Raman spectroscope, and Cyclic Voltammetry (CV) techniques, respectively. The photoelectrochemical current of the MWCNs-P3OT based cell under illumination was investigated by applying a voltage. The blend consisting of 10% MWCNTs in P3OT gave the promising photocurrent in 0.2 M tetra-butyl-ammonium-tetrafluoroborate (TBATFB), electrolyte. Experimental results indicate that photocurrent obtained from MWCNT-P3OT was three times higher than simple P3OT-based conducting polymer. The electrochemical responses of MWCNT-P3OT films in different electrolytes such as 0.2M TBATFB, 0.2 M LiClO4, 1 M H2SO4 and 0.2 M LiBF6 were investigated for comparative photocurrent properties of the photoelectrochemical cell.
