A North Carolina State University researcher discovered a copper-graphene composite that dissipates heat 25 percent faster than pure copper. Full details at X-bit Labs.
“Both the copper-graphene and indium-graphene have higher thermal conductivity, allowing the device to cool efficiently. The copper-graphene composite is also low-cost and easy to produce. Copper is expensive, so replacing some of the copper with graphene actually lowers the overall cost,” said Dr. Jag Kasichainula, an associate professor of materials science and engineering at NC State and author of a paper on the research.
The paper also lays out the manufacturing process for creating the copper-graphene composite, using an electrochemical deposition process.
