“…Therefore, it is necessary to first disperse the graphene or GO nanosheets in an organic solvent, followed by polymer blending in the organic solvent. Therefore, the functionalization of graphene or GO sheets has been carried out in order to change the surface properties of nanosheets, making them more lipophilic and consequently dispersible in organic solvents [24,[68][69][70][71][72][73][74][75]. Ruoff et al [69,70] reported that GO can be chemically functionalized with isocyanate, and dispersed in organic solvents, followed by blending with polystyrene and a chemical reduction step.…”

“…The recent review by Dreyer is an excellent, succinct source of further information on preparation, structure, and reactivity of GO [21]. Many kinds of reducing agents, such as hydrazine [22], NaBH 4 [23], ethylenediamine [24], Al powder [25], ascorbic acid [26], and p-phenylene diamine [27] have been used to reduce GO and disperse the resultant CGR in the solvent, which is beneficial for further nanocomposite preparation and device fabrication. UV irradiation method [28] has also been reported to reduce GO in aqueous dispersion.…”

“…The primary challenging to achieve individual or few-layer graphene is overcoming the strong, attractive van der Waals forces. To date, chemical efforts at graphite exfoliation have been mainly focused on the intercalation, chemical modification, oxidation-reduction, and the use of stabilizers such as surfactants or polymer [10][11][12][13][14][15][16][17][18][19][20]. However, the most common technique for exfoliation and dispersion of graphene is to disperse the graphite oxide (GO) into water or other polar solvents [21][22][23][24][25].…”
