BRENT: Recent studies show that graphene-based film can be an efficient method to cool electronics. Researchers at Chalmers University of Technology used thermal conductivity capacity to create a film and this capacity was four times that of copper. This graphene film is attachable to electronic components that are made of silicon. As a result it improves the film’s performance when compared to typical characteristics of grapheme that emerged in previous alike experiments.
Due to the high demand for continuous improvement of functionality, it is common for electronic devices to easily be overheated. But, it is essential for the device to be adjusted to adapt to overheating when prolonging electronic lifespan. This could also, result in considerable save in energy usage.
Researchers at this university discovered few years ago that grapheme can hold a cooling effect on silicon-based electronics, prompting new studies on the cooling of silicon-based electronics that incorporate graphene.
Johan Liu, a professor at the university shares that the methods that have been in the working all this while have only generated questions for the researchers. He added that it became unavoidable that those methods cannot assist in eliminating great levels of heat from electronic devices. This is because they have consisted only of a few layers of thermal conductive atoms.
Prof. Liu says that adding more layers of graphene resulted in the issue of adhesiveness. When more layers of graphene were added, the grapheme would not stick to the surface; since the adhesion is held together only by weak Van Der Waals bonds.
