Abstract:
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.

Claim (Index 21):
A nanocomposite film, the nanocomposite film formed by a process comprising:\n preparing a mixture by dispersing a polyvinyl alcohol polymer, one or more of single walled carbon nanotubes and multiwalled carbon nanotubes as a conductive nanofiller, and a polysaccharide into water; casting the mixture to form a casted composition having a polymer phase, a conductive nanofiller phase, and a polysaccharide phase, whereby during the casting, the mixture separates into the polymer phase, the conductive nanofiller phase, and the polysaccharide phase:\n wherein the conductive nanofiller phase is sandwiched between and in continuous contact with the polymer phase and the polysaccharide phase, \n wherein the polymer phase contains a majority of the polyvinyl alcohol polymer in the casted composition, \n wherein the conductive nanofiller phase contains a majority of the single walled carbon nanotubes and multiwalled carbon nanotubes conductive nanofiller in the casted composition, and \n wherein the polysaccharide phase contains a majority of the polysaccharide in the casted composition; and \n drying the casted composition to form the nanocomposite film having a polymer layer, a conductive nanofiller layer, and a polysaccharide layer, wherein the polymer layer, the conductive nanofiller layer, and the polysaccharide layer are respectively formed from the drying of the polymer phase, the conductive nanofiller phase, and the polysaccharide phase:\n wherein a surface of the polysaccharide layer has a first product of electrical resistance and area, R\u00b7A, \n wherein a surface of the polymer layer has a second product of electrical resistance and area, R\u00b7A, and wherein the second R\u00b7A is less than or equal to the first R\u00b7A.
