Abstract

Chemically derived graphene (CDG), as produced by exfoliation and reduction of graphite oxide with natural graphite as the low-cost raw material, is decorated by abundant intrinsic functionalities and lattice defects, which increased the solvent compatibility for tunable surface chemistry and macroscopic assembly for advanced energy storage and thermal management applications. Since the production of kilogram scale graphene has been achieved in our pilot plant located in Taiyuan on Dec 2013, the exploitation for commercial applications of which become a great challenge to the sustainable development of graphene.

As the low dimensional nano-carbons, the ultralow bulk density of CDGs (3~5 g/L) make the material inconvenient for industrial processing. This inspirits us to fabricate macro-assemblies or nanocomposites as an easier form for real application of graphene. As the amphiphilic soft-matter, graphene oxide can be facially dispersed in aqueous solution to form the stable hydrogel, which can be employed as the basic building block and cost effective precursor for macroscopic assembly of graphene. For instance, the flexible C/C composite films, with hierachical structure and tunable surface were constructed by graphene and other carbon sources (carbon fiber, pitch or resin). The materials exhibit an ultrahigh in-plane thermal conductivity of 800~1300 W/m.K with excellent tensile strength of 15~20 MPa, are of great potential as lateral heat spreaders for heat removal in electronics, PV systems and LEDs.
