Despite being a good heat conductor, graphene has its own fair share of problems associated with it too. For instance, the heat easily passing through the surface of stacked graphene, but showing problems with conduction when it comes to a number of layers of the material. Scientists at the rice University are thinking to find a solution to this problem by using a 3D variant of this graphene.
For making these 3D structures of white graphene a reality, the scientists used Boron nitrade nanotubes since these help in heat transfer without any obstructions. The findings of this research will pave the way for a different and a better way to conrol heat. Plus this could cool down any hightly efficient and smaller electronic device (Yes, that includes your smartphones).
According to scientists at the Rice University, boron nitride having a three-dimensional structure could help in keeping small electronics cool. Navid Sakhavand and Rouzbeh Shahsavari from Rice university have come up with the first hypothetical analysis of use of 3-D boron nitride as a tunable material for controlling the heat flow in these kind of devices.
The work carried out by researchers has been published in the American Chemical Society journal Applied Materials and Interfaces.
According to him, “Typically in all electronics, it is highly desired to get heat out of the system as quickly and efficiently as possible. One of the drawbacks in electronics, especially when you have layered materials on a substrate, is that heat moves very quickly in one direction”. However, he added that it doesn’t behave in same manner when it comes to movement of heat from layer to layer.
