graphene paper by pillared with carbon black
graphene paper pillared by carbon black (CB) nanoparticles can be obtained by
introducing inexpensive CB nanoparticles as spacer [ 59 ]. With the similar vacuum
filtration method, restacking of graphene sheets can be greatly mitigated during the
assembly process (Fig. 6 ). The pillared graphene paper exhibit excellent electro-
chemical performances and cyclic stabilities compared with graphene paper
without the addition of CB nanoparticles when used as supercapacitor electrodes.
The specific capacitances of the pillared GP electrode were calculated to be
