Graphene d spacing

WebAug 2, 2013 · Even if the packing density of the graphene stack was reduced by half to 1.1 g/cm 3, the interplanar spacing would be only ~0.67 nm (fig. S1). The ion diffusion and adsorption in such small-size channels is very sensitive to pore size, surface wettability, and particularly the pore interconnectivity ( 4 , 11 , 12 ).
