Fabrication and Application Explorations of Graphene Materials(2)

2014中国国际石墨烯创新大会(Grap-China 2014)——There are challenges of how to realize large-scale fabrication of high-quality graphene microstructures and large-size single crystal graphene domains, which are essential for mass and device applications. In order to commercialize graphene materials, we developed a solid state intercalation-high temperature expansion-liquid phase exfoliation process.Second,we developed an ambient pressure CVD to synthesize millimeter-size single crystal graphene grains and films on Pt substrates, and an electrochemical bubbling method to transfer these grains and films, which is also non destructive to the Pt substrates that can be repeatedly used for graphene growth with no limit.Finally, in order to obtain graphene by CVD in a relatively large quantity, we tried to use Ni particles and Ni foams as substrates. Interestingly, with a Ni foam as template, a 3D graphene microstructure, which is called graphene foam(GF), can be synthesized.
