Abstract
Graphene composite material and devices using the same. The graphene is dispersed in material such as polyurethane, latex, other elastomers, and other polymers to produce a composite material having high heat transfer properties which make it particularly suitable for use in removing heat from LEDs and other electronic devices. Several examples of heat transfer devices utilizing the material are disclosed.
