“…The results showed that nanocomposites with melaminefunctionalized nanofillers presented higher tensile strength and fracture resistance than nanocomposites that had nonfunctionalized nanofillers [53]. Similarly, in the work reported by Min et al, on nanocomposite polyimide using amine-functionalized graphene nanosheets, an increase in thermal stability, mechanical properties, and tribological performance was evidenced, when compared to non-functionalized graphene nanosheets nanocomposites [54].…”

Nanocomposite polymers have received considerable interest in research for the last three decades. Those nanocomposite polymers that are sensitive to a stimulus such as pH, temperature, magnetism, and electricity, among others, called smart or intelligent nanocomposite polymers had received even greater attention due to their potential technological applications. Applications of these polymers include flexible electronic devices, sensors, self-healing polymers, shape-memory materials, etc. The sensitivity of the material can come from both the polymer that acts as a matrix and the nanofiller, resulting in a material that combines properties of each of its components and that each one will not have separately. This mini-review aims to provide an update on the most recent and significant applications in the area of stimuli-responsive polymer nanocomposites, emphasizing the most innovative applications in biomedicine and catalysis developed in the last three years.

“…Raman spectra were also carried out to characterize defects on graphene materials. In Figure B, the Raman spectra of rGO and FGO exhibited D (~1360 cm −1 ) and G (~1580 cm −1 ) bands which were two characteristic bands of graphene . Usually, the G band is resulted from sp 2 carbon atoms vibrating in the plane, while the D band is known as a disordered vibration band revealing structural defects in the graphene sample.…”

Novel polyimide/fluorinated graphene oxide (PI/FGO) nanocomposites with outstanding mechanical, thermal, and tribological properties were obtained using FGO nanosheets which were successfully fabricated by simple hydrothermal reaction. FGO exhibited distinguished interface adhesion with PI matrix due to covalent bonds, resulting improved mechanical and wear resistance of PI/FGO nanocomposites. Wherein, PI/FGO‐0.5 nanocomposite demonstrated conspicuous tribological performance accompanied with 33.1% decrease of friction coefficient and 80.8% reduction of wear rate compared with pure PI under dry friction. Notably, PI/FGO nanocomposites manifested better wear resistance under seawater than that under dry friction, illustrating its great potentiality as high wear‐resistant material suitable for ocean environment.

“…Further investigations show that nanomaterials with two dimensional (2D) layered structures such as graphene/graphene oxide [11], MoS 2 nanosheets [12], and hexagonal boron nitride (h-BN) nanosheets [13] have superior characteristics such as large specific surface, ease of shear, and good self-lubricating properties. In this regard, investigations have demonstrated that adding 2D layered nanomaterials greatly improves the tribological performance of polymers.…”

Studies show that two dimensional (2D) nanomaterial and its hybrid have a great promise in tribology for the special laminar microstructure. However, the majority of performed investigations about 2D graphitic carbon nitride (g-C3N4) nanosheets are most focused on energy storage, catalysis, adsorption, rarely tribology. In the present study, g-C3N4 supporting mono-dispersed Ag nanoparticle hybrid (g-C3N4/Ag) is prepared, and its microstructure and chemical composition are determined. More specifically, the tribological performance as the lubricating additive of poly phthalazinone ether sulfone ketone (PPESK) composite is investigated using the ball-on-disc friction tester. Moreover, the corresponding enhancement mechanism is well proposed based on the experimental analysis and theoretical simulation. Obtained results show that Ag nanoparticles with a size of about 10–20 nm are homogeneously anchored on g-C3N4 nanosheets, favoring for good compatibility between g-C3N4/Ag and PPESK. It is found that when 0.3 wt% of g-C3N4/Ag is added to PPESK, the friction coefficient and wear rate of PPESK decrease by 68.9% and 97.1%, respectively. These reductions are mainly attributed to the synergistic self-lubricating effect of Ag nanoparticles and g-C3N4 nanosheet, the formation of transfer film, as well as the limited effect of g-C3N4/Ag on the shear deformation of PPESK composite film. Furthermore, it is found that the proposed g-C3N4/Ag-PPESK composite still keeps reasonable friction-reducing and wear-resistant properties under heavy loads and high rotating speeds. The present study demonstrates that the proposed g-C3N4/Ag hybrid is an excellent lubricating additive for polymer composites.
