Nanocomposite films comprising carbon nanotubes dispersed throughout a polymer matrix and further comprising at least two surfaces with differing amounts of carbon nanotubes and differing electrical resistivity values are provided. Nanocomposite films comprising a polymer layer, a conductive nanofiller layer, and a polysaccharide layer having antistatic properties are provided. In particular, nanocomposites comprising polyvinyl alcohol as the polymer, graphene as the conductive nanofiller and starch as the polysaccharide are provided. In addition, processes for forming the nanocomposites, methods for characterizing the nanocomposites as well as applications in or on electrical and/or electronic devices are provided.
