  The morphology and the chemical characteristics of graphene nanoplatelets are
important parameters to define the potential of these particles in various
applications. In this paper we firstly conducted a market analysis to identify
commercial CIG (Graphite Intercalation Compounds) with different
characteristics, our selection was based on physical-chemical criteria (such as
purity, mesh, expansion degree) and commercial (cost, availability, etc). The
materials were prior expanded and exfoliated on a laboratory scale, then on an
industrial pilot plant, to study the final characteristics of the graphene
nanoplatelets and the relations of them to the starting materials. Selected
materials and products, derived from the exfoliation process, have been well
characterize; SEM, OM, XRD, PSA, BET for the morphological characteristics and
TGA, FT-IR, XRF, EDS for chemical ones. We have obtained particles with
different chemical-physical characteristics, potentially suitable for
applications that request to improve electrical and thermal conductibility
and/or mechanical reinforcement and/or barrier effect
