Acceptor type GIC

Other methods were also successfully used to synthesize acceptor-type bi- and co-intercalation compounds. Schoderbock and Boehm prepared stage-2 Cjg (AICI3 3)o.7(NbCl5)o.33 by the subsequent intercalation of AICI3 into stage-3 NbCIs-GIC in a saturated SOCI2... 

As already mentioned the fundamental condition which must be fulfilled for intercalation to occur is electron transfer from the graphite macromolecule to intercalate or vice versa. This quantity determines directly many physiocochemical properties of GICs. For example, it is obvious that for an acceptor compound the quantity of electrons lost by the graphene layers (some other time understood as the hole concentration), must exactly be compensated by the amount of electrons accumulated in the intercalate layers to assure the electrical balance of the intercalation system. The formation of acceptor and donor-type compounds in the reactions of anodic oxidation and cathodic reduction may be represented by the following equations, respectively,... 

Despite a vast amount of experimental data the mechanism of exfoliation has not been established yet. The reason for this arises from the fact that the kinetics of exfoliation depend on many factors, e.g. the type of precursor (acceptor or donor GIC), the properties of the original graphite, the preparation method of the GICs as...
