Аннотация:It was found out that nanotubes can form stable aqueous dispersion in the presence of all studied PVPs. The extent of ethylated PVP quaternization is likely to have an influence on interaction of this polymer with nanotubes and surrounding aqueous media as well. However, the composition of soluble CNT-PVP complexes and maximum achievable concentration of CNT in solution were found to be almost independent upon the quaternization degree of ethylated PVP. Preapared CNT-PVP composites are found to be highly electrically conductive. Conductivity of CNT complexes with ethylated PVP is reaching 100 S/cm, which is higher by almost an order of magnitude in comparison with conductivity of pristine CNT.
