(April 29, 2016) Recently, a team of researchers from Chalmers University of Technology in Sweden have developed a more efficient approach to cooling electronics using graphene nanoflake-based film.
According to E&T, the team performed “experiments in which they managed to increase the efficiency of heat transfer by 76 per cent” – the kind of results that suggest “potential thermal management solutions for electronic devices.”
“The graphene-based film was further enhanced by adding functionalised amino-based and azide-based silane molecules,” E&T reported, “In simulations, the researchers observed how the functional layer constrained the cross-plane scattering of low-frequency phonons, which in turn enhances in-plane heat-conduction of the bonded film.”
“In the research, scientists studied a number of molecules that were immobilised at the interfaces and at the edge of graphene nanoflake-based sheets forming covalent bonds. They also probed interface thermal resistance by using a photo-thermal reflectance measurement technique to demonstrate an improved thermal coupling due to functionalisation,” according to E&T.
The research was published in the journal Nature Communications.
