Detailed explanation-1: -The most outstanding properties of graphene are: High thermal conductivity. High electrical conductivity. High elasticity and flexibility.
Detailed explanation-2: -Graphene has revealed another of its extraordinary properties. Researchers in the UK at the University of Manchester have found that it is super-permeable with respect to water.
Detailed explanation-3: -Graphene is the most impermeable material owing to (a) the closed-spaced carbon atoms in graphene, (b) the high electron-density (-cloud) which repels all molecules, (c) the high strength, and (d) its ultrathin (thinnest) structure.
Detailed explanation-4: -A greyish black, opaque substance. Lighter than diamond, smooth and slippery to touch. A good conductor of electricity( Due to the presence of free electrons) and good conductor of heat. A crystalline solid. Very soapy to touch. Non-inflammable. Soft due to weak Vander wall forces.
