Abstract


  • Conducting composite films containing carbon nanotubes (CNTs) were prepared by using the biopolymer kappa-carrageenan (KC)

    as a dispersant. Rheological studies indicated that 0.5% w/v was the appropriate KC concentration for dispersing CNTs. Our results

    showed that multiwalled nanotubes (MWNTs) required less sonic energy than single-walled nanotubes (SWNTs) for the dispersion

    process to be complete. Films prepared by vacuum filtration exhibited higher conductivity and improved mechanical characteristics

    compared to those prepared by evaporative casting. All composite films displayed sensitivity to water vapour, but MWNT films

    were more sensitive than SWNT films.
