Fabrication of freestanding thin-film composite electrodes by electrodeposition was first reported by Wang et al. [85]. In this work, freestanding and flexible graphene composite paper was used as the working electrode on which a PANi film was formed by an in situ anodic electropol mierization technique... 

Using a dynamic collection of droplets in a gas medium is also a well-known procedure to restrict the reaction volumes and obtain nanoparticulate materials by a thermally promoted reaction (spray pyrolysis]. Chidembo et al. [112] used an in situ spray pyrolysis approach to fabricate metal oxide-graphene composites with highly porous morphologies. The materials exhibited unique globular structures comprising metal oxide nanoparticles intercalated between graphene sheets. 

In a different attempt made by Zhang et al. to fabricate Au NPs-graphene composites via redox reaction between Au salt solution and GO nanosheets, an aqueous solution of HAuCl was mixed with GO and subsequently the solution was heated at 84°C for 15 min. The formation of Au NPs-rGO composites and the variation of their morphology with concentration of the reactants were executed using transmission electron...

The three most common methods of fabricating graphene-based polymer composites are described below. 

Due to the electrochemical instability of GO, GO-PANI composites cannot take advantage of the good properties of GO. Reduced GO would be more favorable for the preparation of PANI composites. Zhao et al. fabricated graphene/PANI nanofibre composites through an in situ polymerization of aniline monomer in the presence of GO under acid conditions, followed by the reduction of GO to graphene using hydrazine. The composite that contained 80 wt% rGO showed the highest specific capacitance of 480 F/g at a current density of 0.1 A/g.
