Preparation and Tribological Study of Functionalized Graphene–IL Nanocomposite Ultrathin Lubrication Films on Si Substrates

Carbon quantum dot/CuSxnanocomposites towards highly efficient lubrication and metal wear repair

“…Inorganic compounds have been widely used as additives in lubricating grease and fillers in polymer/substrates to decrease the tribological behaviour. [4][5][6][7][8][9][10][11] However, the practical application of inorganic nanoparticles as additives in lubricating oils is severely limited, owing to their poor dispersion capacity in oils. The organic-inorganic composite materials, such as, DDP-coated MoS 2 , Mo-S compounds, and organic acid coated TiO 2 , exhibited good dispersion capacity and excellent antiwear behavior in liquid paraffin.…”

Tribological and mechanical investigation of MC nylon reinforced by modified graphene oxide

“…Graphene oxides combining with the excellent properties of neat graphene, rich surface functional groups and low cost, are expected to be promising nano-scale filler for the next generation of functional composite materials [14]. Until recently, tribological studies on graphene preliminarily focus on the microscopic study of the tribological properties [15][16][17][18][19][20][21], solid lubrication film and coating [22][23][24][25][26][27] and lubricant additive [28][29][30]. There is little information available about the discussion of friction and wear behavior of monolithic polymer nanocomposites reinforced by graphene [31,32].…”

High performance, All solid state, flexible Supercapacitor based on Ionic liquid functionalized Graphene

“…The appearance of additional methylene antisymmetric and symmetric stretching vibrations at 2927 and 2846 cm À1 confirmed deoxygenation with restoration of conjugation. Furthermore, restored aromatic yC¼C (1690 cm À1 ) and additional bands corresponding to yC-N and yC-H of imidazole at 1516, 1344, 1190 and 1052 cm À1 demonstrate the successful functionalization of graphene with [BMIM][BF 4 ] [21,29]. XRD spectrum of GO (Fig.…”

“…In the context, Kerisit [19] and Fedorov [20] suggest the existence of ionic liquid cation anion pairs in dense layer on graphene surface with preferential orientation of the cation imidazolium rings in these layers is parallel to the surface. Surface charge so generated enhanced electrostatic adsorption of gel electrolyte, resulting in double layer formation [21,22]. [EMIM] [BF 4 ], owing to its small cation size, possess high conductivity in wide operating potential [23] resulted in a supercapacitor with excellent capacitance and high GCD cycling stability.…”
