with a cylindrical shape, 15 mm in diameter and 7 mm in thickness, followed by sintering at 700 °C for 2 h under argon gas. The electrical conductivity and hardness were tested on a 7501 eddy electrical......
of graphene make it close to ideal reinforcing materials in the carbon family [16]. The thickness of monolayer graphene sheet is only 3.35 , while its theoretical elastic modulus and intrinsic strength.... [19] BLANTER Y M, MARTIN I.
