Graphene tech promises to increase cooling efficiency

updated 07:45 pm EDT, Mon April 9, 2012

Copper-graphene composite said to be low cost

Researchers at North Carolina State University have reportedly developed a new form of graphene technology that is claimed to be suitable for electronics cooling systems. The copper-graphene composite materials are said to bring a 25 percent improvement in thermal conductivity compared to pure copper.

"Both the copper-graphene and indium-graphene [interface film] have higher thermal conductivity, allowing the device to cool efficiently," said NC State associate professor of materials science and engineering Dr. Jag Kasichainula.

Although many new electronics technologies are prohibitively expensive, the electrochemical deposition process used to manufacture the copper-graphene composite is said to be "low-cost and easy to produce," according to the researchers.

"Copper is expensive, so replacing some of the copper with graphene actually lowers the overall cost."

The research paper has been published in Metallurgical and Materials Transactions B.
