Surface area of graphene
WebDec 28, 2024 · According to theoretical estimates, the specific surface area of graphene is 2630 m 2 /g [ 9 , 10 ]. Indeed, individual sheets obtained during the synthesis of graphene form agglomerates and/or have defects, so the real specific surface is usually 150–600 m 2 /g (less often about 2000 m 2 /g). WebSince 2004, scientist continue research on Graphene’s novel properties such as the bipolar transistor effect, magnetism, ballistic transport of charges and large quantum oscillations …
