[" 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."
So, when WE apply it to our connections, are we in effect eliminating the copper in the connections and replacing it with graphene?"]
My take on it is that if properly formulated and applied then the Graphene will form a highly stable, hydrophobic, highly conductive interface between the copper (or whatever the conductive interfaces are).
