According to foreign media reports, making every micron valuable is a key consideration for modern smartphone designers and engineers, and a new material can release some valuable space. Scientists have developed a graphite form of nanometer thickness that helps keep electronic devices cool and, in doing so, takes up only a fraction of the space in current solutions. < / P > < p > graphite films play an important role in keeping many electronic devices cool, and their excellent thermal conductivity is used to neutralize the heat generated by the surrounding components. However, it is not easy to make them. It is necessary to go through several processes and put the materials at an extreme temperature of 3200 ° C to produce films with a thickness of about a few microns. < / P > < p > “using polymers as source materials to make these graphite films is complex and very energy intensive,” said g. deokar, who led the new study. < / P > < p > deokar and his colleagues at King Abdullah University of science and Technology (kaust) in Saudi Arabia have been working on a more efficient way to produce these graphite cooling devices. The technology involves the conversion of hot methane gas to graphite using nickel foil as catalyst. The thickness of graphite film formed on the surface of nickel foil is only 100 nm. < / P > < p > the team calls these films nano thick graphite films (ngfs) produced by exposing the material to a temperature of about 900 ℃. In this process, ngfs are formed on both sides of the foil and can grow into 55 square centimeter (8.52 inch) thin sheets. These films can be extracted and transferred to other surfaces. < / P > < p > these ngfs are much thinner than the currently used micron thick graphite films, but they are still much thicker than single-layer graphene. It may provide a degree of flexibility and robustness in this way, with lower production costs for these materials, the researchers said. < / P > < p > these conductive and translucent films can be used not just to keep mobile devices cool. The researchers say their versatility can be seen in their use as solar cell modules or sensors for detecting nitrogen dioxide gas. “We plan to integrate ngfs into the device as a multifunctional active material,” Costa said.
