“…Since corrosion is an age-old problem, several mitigation strategies have been investigated and adopted with different degrees of success. The use of graphene as an ultra-thin coating has emerged as a novel and exciting approach to the corrosion protection [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The remarkable properties of graphene include its very high charge carrier mobility [ 17 , 18 ], high optical transparency (97.7%) [ 19 ], flexibility (spring constant 1–5 N/m) [ 20 ], a breaking strength 100 times greater than the strongest steel with a tensile modulus (stiffness) of 1 TPa [ 21 ], scratch resistance [ 22 ], record electrical conductivity [ 23 ], the highest current density (million times that of Cu) [ 24 ] and thermal conductivity of (4.84 ± 0.44) × 10 3 to (5.30 ± 0.48) × 10 3 Wm −1 K −1 (outperforming diamond) [ 25 ], impermeability even to the smallest atomic size gas (i.e., He) [ 26 ], and chemical inertness [ 27 ].…”

Ultra-thin graphene coating has been reported to provide considerable resistance against corrosion during short-term exposures, however, there is great variability in the corrosion resistance due to graphene coating in different studies. It may be possible to overcome the problem of hampered corrosion protection ability of graphene that is caused due to defective single layer graphene by applying multilayer graphene. Systematic electrochemical characterization showed that the multilayer graphene coating developed in the study provided significant corrosion resistance in a chloride solution and the corrosion resistance was sustained for long durations (~400 h), which is attributed to the multilayer graphene.

“…For example, graphene can be functionalized using hydrolyzed 3-(Aminopropyl)triethoxysilane (APTES) by forming bonds due to the attraction between the amino group of APTES and free electrons of the graphene edge. This type of functionalization helps graphene form a "chemical network" with the underlying metal to reduce corrosion ( Figure 12) [160,161].…”

Metal deterioration via corrosion is a ubiquitous and persistent problem. Ångstrom-scale, atomically thin 2D materials are promising candidates for effective, robust, and economical corrosion passivation coatings due to their ultimate thinness and excellent mechanical and electrical properties. This review focuses on elucidating the mechanism of 2D materials in corrosion mitigation and passivation related to their physicochemical properties and variations, such as defects, out-of-plane deformations, interfacial states, temporal and thickness variations, etc. In addition, this review discusses recent progress and developments of 2D material coatings for corrosion mitigation and passivation as well as the significant challenges to overcome in the future.

Carbon is a unique chemical element whose different forms or allotropes are inexhaustible in number. It has been in use since antiquity and now, the possibility of manipulating the lattice structure of its crystalline allotropes, offers it unlimited advanced applications. This review aims at demonstrating certain aspects of engineering material in different applications. Various structures of some identified allotropes carbon, respective properties and uses of the allotropes were reviewed. Amorphous carbon materials find application mainly as fuels and sometimes as parent materials for synthesis of more useful chemicals. Their limited application was ascribed to their unstable irregular patterned structure which cannot be manipulated easily to meet further needs. Structurally, carbon exists in the sp3 and sp2 hybridized state in the crystal lattice of its crystalline allotropes. Due to the salient features of its allotropes, carbon finds application in energy generation and storage, optics, electronics, opto-electronics, electro-catalysis, corrosion control, bio-sensing (diagnostics), sensing, agriculture, water treatment, making of composite materials with unique properties and more. There is no limit to the application of carbon. It was recommended that renewable and sustainable alternative precursors for synthesis of carbon nanomaterials with crystal growth control be sought for.
