Research On Fabrication And Application Of Novel3D-graphene

Three-dimension （3D） graphene of excellent electrical conductivity, large surfacearea and3D cross-linked porous structure has attracted increasing attentions.Recently, chemical vapor deposition （CVD） is the main method to preparehigh-quality3D graphene, which employ metal foams （Ni, Cu etc.） as catalysttemplates. Although, it is facile to obtain the high-quality graphene, the issues of highporosity, low density and weak mechanical strength restrict the practical applicationsof3D graphene. Therefore, it is significant to synthesize high-quality andhigh-density3D graphene by a facile, rapid and high efficiency process. Herein, wedevelop a rapid CVD synthesis of high-density3D-GMOs grown on3D porouscross-linked Ni skeleton catalysts fabricated by the reduction of nickel chloridehexahydrate （NiCl₂·6H₂O） crystalline. After etching the templates, we obtain the3Dgraphene with high density, large surface area and high conductivity. The as-prepared3D graphene/PDMS composites exhibit better mechanical performance than that ofNi foam-based3D graphene. The new high-density3D-GMOs with the outstandingproperties fabricated by this highly efficient CVD technique have significant potentialapplications for the polymer composites, energy-storage composite materials,thermally conductive media, catalyst supports, electromagnetic interference shieldingmaterials and so on.
