Detailed explanation-1: -Graphene stands out for being tough, flexible, light, and with a high resistance. It’s calculated that this material is 200 times more resistant than steel and five times lighter than aluminum. With these properties, graphene has applications in the energy, construction, health, and electronics sectors.
Detailed explanation-2: -But despite the material’s appearance, studies have shown that defect-free graphene is nearly impermeable.
Detailed explanation-3: -Graphene nano-platelets have several fascinating properties, including their low weight, high surface-to-volume ratio, electrical/thermal conductivity, mechanical strength, and inexpensive and planar form. However, graphene sheets have orders of magnitude higher electrical conductivity than graphene oxide.
