Being one of the most lightweight, toughest, and most flexible materials in the world, having exceptional mechanical, electrical, thermal, and tribological properties, makes graphene and its several based materials crucial applicants for biomedical, medical, aerospace, automotive, electrical, energy, sensing, food, and other industrial sectors. Graphene is classified as a carbon allotrope, with one-thick-atom planar 〖sp〗^2 layers of attached carbon atoms tightly loaded within a crystal honeycomb lattice. Various techniques to produce graphene were established over a brief period of time, including top-down and bottom-up methods. Graphene itself can be used as a coating to improve other materials; likewise, it could be added to further composite materials. This review recaps the applications of graphene, its types, synthesis methods, and mechanical, tribological, and thermal characteristics, in addition to enhancement methods for graphene and its based materials.

Reinforced AA1170 aluminium alloy with particulates of Bos taurus (BT) and Cocos nucifera (CN) (0% to 20% wt. concentration) was evaluated for their corrosion resistance properties in 3.5% NaCl and 0.05 M H 2 SO 4 solution by potentiodynamic polarization, open circuit potential analysis, potentiostatic analysis, optical and scanning electron microscopy and x-ray diffractometry. Results showed corrosion rate of monolithic aluminium alloy (0% particulate wt. concentration) from both electrolytes (3.5% NaCl and 0.05 M H 2 SO 4 ) are 0.204 and 0.259 mm/y. Corrosion rate of BT reinforced composites from both solutions decreased with respect to BT particulate concentration to 0.087 and 0.216 mm/y at 20% BT. Whereas corrosion rate of CN reinforced composites decreased to 0.161 mm/y in 3.5% NaCl and increased to 0.434 mm/y in 0.05 M H 2 SO 4 at 20% CN concentration. The most passivated aluminium composites from polarization plots occurred 5% BT and CN particulate concentrations. Increase in particulate concentration results in vulnerability to localized corrosion. Open circuit potential plots show the presence of the particulate reinforcements increased the thermodynamic instability of the surface properties of the composite and its exposure to active-passive transition behavior. Optical and scanning electron microscopy indicates signi cant improvements in the corrosion resistance of BT and CN particle reinforced aluminium compared to the unreinforced alloy were signi cant surface deterioration, pitting corrosion and intergranular corrosion were presence. X-ray diffractometry showed the phases identi ed for BT particle reinforced composite (Al 2 O 3 , Cu S 2, Zn S 2, ZnCO 3 and CuO 2 ) signi cantly enhances it corrosion resistance compared to the monolithic and CN particle reinforced composite.
