PANI/exfoliated graphene nanoplatelets (GNs) composites were prepared by similar in-situ polymerization [13]. A paper-like nanocomposite flexible film was obtained by controlling vacuum filtration of an aqueous dispersion of PANI-decorated GNs as shown in Figure 6.6 [14].

Two-dimensional nanostructures have two dimensions outside of the nanometric size range, such as nanoplates, nanosheets, and nanodisks. Graphene is a typical two-dimensional film, which is composed of a one-atom-thick planar sheet of sp -bonded carbon atoms that are densely packed into a honeycomb crystal lattice. This material exhibits a high electrical conductivity, a high surface area of over 2600 m g , an elevated chemical tolerance, and a broad electrochemical window. Therefore, they were used to form two-dimensional nanocomposites with polymers. The graphene not only increases the electrical conductivity of the polymer, but also enhance its mechanical stability. Conducting polymers with various hierarchical structures have been deposited on...

Hu et al. showed the preparation of highly porous nanorod-PANI-gra-phene nanocomposite films deposited onto the ITO substrate by in-situ electrochemical polymerization [135]. They used a reverse micelle technique by mixing oil and water in an aqueous solution of TritonX-100. The electro-migration of the ionic species is improved by the addition of dilute HNOj to the oil-water-surfactant solution followed by the polymerization of aniline monomer in presence of graphene dispersion. Figure 4.12 shows the schematic for the preparation of nanorod-PANI-graphene nanocomposites by reverse micelle in-situ electropolymerization technique.
