Activated carbon fibers (ACFs) possess nanocrystalllites made up of graphene sheets that create conducting particles, nonuniformly distributed in space. The nanocrystallites are about 2.5 nm. Existence of voids makes ACFs a porous system, with specific surface area of 3000 m2/g. In such porous material with conductive particles it is necessary that the grains are linked structurally in order to hold sample together. But the linkage is not always electrical.
