Exfoliated-graphene nanoplatelets

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].

Noncovalent functionalization of graphene is important, as it does not affect the electronic structure and planarity of this 2D material. Stable aqueous dispersions of polymer-coated graphitic nanoplatelets can be prepared through an exfoliation and... 

The relatively low cost of graphite in comparison to CNTs makes exfoliated graphite an attractive material (20). The use of graphite nanoplatelets is advantageous because of the chemistry of the graphene and graphene-Uke sheets compared to clay nanoplates.

GNS are produced by layer-by-layer exfoliation of graphite into oxidised graphene sheets (OGS) followed by a reduction. The thickness of nanoplatelets comprising a stacked assembly of 10 20 layers of GNS lies between 3 and 7 nm (Figure 7.62a). The nanocomposite of (i) GNS and CNT, and (ii) GNS and were prepared by reaction with the addition of single-walled carbon nanotubes and Cgo to GNS, respectively. The first cycle capacity of the reaction sequence samples—graphite, GNS, GNS + CNT and GNS + —are 360, 540, 730 and...
