Researchers say graphene-based film provides an effective way to cool electronics. Thermal captivity was used by researchers at Chalmers University of Technology to create the film. The researchers said its capacity was four times than that of copper.

The researchers say they could attach this grapheme film to electronic components that are made of silicon. This plays a big role in improving the film’s performance much more than typical characteristics of grapheme seen in experiments conducted previously.

Electronic devices overheat easily because of the high demand for continuous improvement of functionality. This gives rise to the need of adjusting the device to overheating.

The researchers figured out a few years ago that it was possible to cool down silicon-based electronics by using graphene. Many researchers started studies on the cooling of silicon-based electronics that incorporate graphene after learning about it potential.

However, the methods that currently exist have not significantly helped researchers solve the problem to a desirable extent. “It has become evident that those methods cannot be used to rid electronic devices off great amounts of heat, because they have consisted only of a few layers of thermal conductive atoms”, said Johan Liu, a professor at the university.

Researchers have published new findings in the silicon-based electronics, revealing that a new graphene-based film is capable of working efficiently to cool electronics.

Liu said they have found the solution to the problem by creating strong covalent bonds between the graphene film and the surface made of silicon.
