Technology
We have sublicensed two patents that are focused on graphene production and roll to roll graphene production. Our mission to utilize the two patents and further develop the technology for our specific applications in the energy storage and water filtration marketplace.
Method of Producing Graphene
Graphene can be produced from the byproducts formed during electrolysis of coal. These byproducts may be electrolyzed coal particles, gelatinous film formed on the electrolyzed coal particles, or the electrolyzed coal particles together with the gelatinous film. The electrolyzed coal byproduct is deposited as a thin layer onto a surface, or carrier substrate, which is heated to a temperature effective to form graphite while a reductant gas, such as hydrogen, flows over the heated coal product. The reductant gas flow carries the carbon particles and deposits them onto a surface, forming a layer of graphene thereon.
Roll to Roll Graphene Production,
Transfer of Graphene and Substrate Recovery
A method of producing a graphene film includes forming a catalyst film on a support; forming a graphene film on the catalyst film; and electrolytically removing the catalyst film from the support. The method may include transferring the graphene film to a substrate. A supported graphene film includes a conductive support; a catalyst film formed on the conductive support having a thickness in a range of 1 nm to 10 um, and a graphene film formed on the catalyst film.
