“…Carbon nanotubes (CNTs) are the one dimensional fibrous allotropes of carbon, discovered by Iijima in the year 1991, [1][2][3] which have drawn the focus of researchers because of their unique set of properties arising from the strong sp 2 near planner hybridisation of C-C bond. 4,5 Versatile application paradigm of CNTs includes electronics, structural composites, medicines, automotive industries and energy storage media, 3,[6][7][8] due to their high aspect ratio 9,10 and outstanding properties, 11,12 like low density (1.3 g/cm 3 ), 13 high elastic modulus (around 1.8 TPa), 14 high tensile strength (up to 300 GPa), 8 high bending strength, 15 exceptional thermo-oxidative stability, 16 low co-efficient of thermal expansion (CTE ¼ 0) 17 and high electrical conductivity. 18 Presently many material scientists emphasise to use CNTs as reinforcements in aluminium matrix composites (AMCs), as the CNTs improve their hardness, strength, toughness, resistance to creep and wear remarkably.…”
