Researchers from the University of California, Riverside and the University of Manchester discovered that coating copper with graphene (on both sides) strongly enhances the heat conducting properties of the copper.

The researchers say that coating the copper with one-layer graphene sheets increased heat conducting properties up to 24%. They say that this method could be used to built better hybrid copper – graphene interconnects for electronic chips. The researchers explain that the improvement is the result of changes in copper’s nano- and microstructure, not from graphene's action as an additional heat conducting channel.
