Just published–graphene’s properties enable its use as a thermal interface material (TIM). In many electronic applications, heat must transfer efficiently from one material to another. The materials aren’t perfectly smooth, so there are voids and grooves between the materials at the interface. TIMs are used to fill in these voids and grooves to enhance thermal conductivity.
“The increase of the thermal conductivity of commercial TIMs from the present 5 W/mK to 25 W/mK would revolutionize not only electronics but also energy generation, for examples solar cells,” Alexander Balandin, a professor of electrical engineering at the UC Riverside Bourns College of Engineering, tells Nanowerk.
