Abstract


  • The mechanical and electrical characteristics of films, buckypapers and fiber

    materials from combinations of clay, carbon nanotubes (CNTs) and chitosan are described.

    The rheological time-dependent characteristics of clay are maintained in clay–carbon

    nanotube–chitosan composite dispersions. It is demonstrated that the addition of chitosan

    improves their mechanical characteristics, but decreases electrical conductivity by

    three-orders of magnitude compared to clay–CNT materials. We show that the electrical

    response upon exposure to humid atmosphere is influenced by clay-chitosan interactions,

    i.e., the resistance of clay–CNT materials decreases, whereas that of

    clay–CNT–chitosan increases.
