NanoXplore has_x000D_
expertise on graphene production at a low cost, large volume and highly scalable. However, NanoXplore needs_x000D_
more information of the conductivity of its own graphene powders and baseline carbon black as a guide to_x000D_
design coating formulations. The new intended applications of graphene-based coating are electrostatic_x000D_
discharge for antenna, of great commercial potential. NanoXplore has an important line of activity in graphene_x000D_
and needs more investigations on several aspects including: coating materials and methods, durability,_x000D_
conductivity. The general objective of this proposal is to measure the conductive of graphene powders (versus_x000D_
other commonly used conductive additives) and its composites (coating and polymer blends) to better_x000D_
understand how to target coating formulation. The specific objectives are the following: 1) benchmark the_x000D_
conductivity of the graphene and carbon black powders; 2) preparation and optimization conductive_x000D_
graphene/polymer coating to dissipate charges from antennae; 3) investigation of the conductivity of_x000D_
immiscible polymer blends (semicrystalline and amorphous polymers). To achieve the objective 1, a protocol_x000D_
was recently developed at ETS to measure the electrical conductivity of solid powders using a high impact_x000D_
polymeric sample container and a 4-wire multimeter. Powder compaction is controlled with a universal_x000D_
mechanical testing machine. To achieve the objective 2, epoxy and polyester coatings are prepared and the_x000D_
graphene content is optimized via the conductivity measurement. In the objective 3, we propose a novel_x000D_
method to prepare ultra-low percolation threshold conductive polymer by controlling the morphology of the_x000D_
blends and the interface. The tangible applications of this research are ultralow percolation threshold_x000D_
conductive polymers, high performance polymer blends and antenna electrostatic discharge materials., program purpose french : Graphene is a two-dimensional monolayer of carbon atoms organized in a hexagonal lattice. NanoXplore has_x000D_
