“…Graphene coating applications have multiple advantages such as increasing the resistance to oxygen and water, improving electrical and thermal conductivities, increasing the hydrophobicity on the surface, and preventing scratching and abrasion. However, the presence of the polymer along with graphene helps their use in coating applications [ 191 , 192 , 193 , 194 , 195 ]. Graphene dispersion in DMF prepared by the jet cavitation method has been used for coating applications, to coat Kapton which enhances the atomic oxygen erosion resistance [ 196 ].…”

Graphene is an excellent 2D material that has extraordinary properties such as high surface area, electron mobility, conductivity, and high light transmission. Polymer composites are used in many applications in place of polymers. In recent years, the development of stable graphene dispersions with high graphene concentrations has attracted great attention due to their applications in energy, bio-fields, and so forth. Thus, this review essentially discusses the preparation of stable graphene–polymer composites/dispersions. Discussion on existing methods of preparing graphene is included with their merits and demerits. Among existing methods, mechanical exfoliation is widely used for the preparation of stable graphene dispersion, the theoretical background of this method is discussed briefly. Solvents, surfactants, and polymers that are used for dispersing graphene and the factors to be considered while preparing stable graphene dispersions are discussed in detail. Further, the direct applications of stable graphene dispersions are discussed briefly. Finally, a summary and prospects for the development of stable graphene dispersions are proposed.

“…Recently, as a potential remedy to resolve this issue, graphene (Gr) in the form of a thin layer (i.e., Gr coating) has received extensive attention due to its desirable combination of mechanical robustness, thermal conductivity, and tribological properties [ 5 , 6 , 7 , 8 , 9 ]. According to the results, Gr coated on various substrates, including polymers [ 10 , 11 ], aluminum alloys [ 12 ], and steels [ 4 , 13 , 14 ], can effectively improve their frictional and wear resistance properties. In addition, there are several factors affecting the improvement of both properties, such as Gr film thickness [ 15 ], structural defects of Gr [ 9 ], surface chemistry of Gr [ 16 , 17 ], and substrate properties [ 18 ].…”

Effects of the Transfer Method and Interfacial Adhesion on the Frictional and Wear Resistance Properties of a Graphene-Coated Polymer

Graphene is a promising candidate used to reduce friction and wear in micro- and nano-device applications owing to its superior mechanical robustness and intrinsic lubrication properties. Herein, we report the frictional and wear resistance properties of a graphene-coated polymer and how they are affected by fabrication processes. The results show that graphene deposited on a polymer substrate effectively improves both frictional and wear resistance properties, and the degree of improvement significantly depends on the graphene transfer method and interfacial adhesion between graphene and the substrate. Dry-transferred graphene showed better improvement than wet-transferred graphene, and the strong adhesion of graphene achieved by imidazole treatment aided the improvement. A combined analysis of surface morphology and scratch trace shows that the graphene transfer method and graphene adhesion dominate the structural integrity of the transferred graphene, and the graphene/substrate interfacial adhesion plays a decisive role in the improvement of both properties by suppressing the delamination of graphene from the substrate during the nanoscratch test, thereby preventing crack formation in graphene and weakening the puckering effect.
