Mechanical Strengths
Bond length is .142 nm long = very strong bond
Strongest material ever discovered
ultimate tensile strength of 130 gigapascals compared to 400 megapascals for structural steel
Very light at 0.77 milligrams per square metre, paper is 1000 times heavier
Single sheet of graphene can cover a whole football field while weighing under 1 gram
Also, graphene is very flexible, yet brittle (preventing structural use)
