New Technology Using Graphene based film could keep electronic gadgets cooler

Researchers at Chalmers University of Technology in Sweden have developed a graphene based film which can keep electronic circuits and gadgets cool. The solution offered by Swedish research team, based on graphene based film, has been published in the current issue of journal Advanced Materials.

Graphene has been accredited with amazing capabilities and strength. The single atom carbon layer could be a game changer for the electronics industry. Many teams across the world are working on projects related to graphene which could change the way we use electronic gadgets today.

Graphene offers cooling effect on silicon based electronic systems. While adding more processing power to electronic equipment and circuits, the biggest problem faced by industry is the heating of those gadgets. Nearly 50 percent of the energy required in computer systems is used for cooling purposes.

The current research project has reported significant reduction in heat in the circuits. By using graphene film on silicon-based electronic circuits, the research team led by Johan Liu has reported amazing outcomes. With the graphene coating, the research team managed to achieve thermal conductivity levels of 1600 W/mK.

In the research paper, Liu said, “We have now solved this problem by managing to create strong covalent [silane] bonds between the graphene film and the surface, which is an electronic component made of silicon.”

After testing a number of additives, researchers found that treating the graphene with (3-Aminopropyl) triethoxysilane (APTES) molecules — as well as a heating and hydrolysis — was the best way to create extra sticky silane bonds between the graphene film and the electronic component.

Liu added, “Increased thermal capacity could lead to several new applications for graphene. One example is the integration of graphene-based film into microelectronic devices and systems, such as highly efficient Light Emitting Diodes (LEDs), lasers and radio frequency components for cooling purposes.”

With amazing applications of graphene, the wearables industry is also looking forward to many new technological applications of the wonder material.
