Multilayer stealth nanostructure with graphene heat conducting layer

Abstract

The invention relates to a multilayer stealth nanostructure with a graphene heat conducting layer. The multilayer stealth nanostructure comprises a micro-channel heat dissipating layer, wherein a thermoelectric conversion layer is disposed over the micro-channel heat dissipating layer; the upper surface of the thermoelectric conversion layer is provided with a groove and is covered with the graphene heat conducting layer; and a light absorbing layer is disposed above the graphene heat conducting layer. The multilayer stealth nanostructure with the graphene heat conducting layer firstly converts light into thermal energy and then converts the thermal energy into electrical energy. The infrared absorbed energy is converted into collectable energy, which can be directly utilized, through light-thermo and thermo-electric conversion. Therefore, not only the stealth effect and the service life of the infrared stealth material are enhanced, but also the graphene heat conducting layer has goodthermal conductivity and enhances heat transfer efficiency. The graphene heat conducting layer is disposed on the surface of the groove to enhance the contact nep between the graphene layer and the thermoelectric conversion layer, thereby further enhancing the heat transfer efficiency and facilitating the efficiency of conversion from thermal energy into electrical energy.

Description

technical field [0001] The invention belongs to the technical field of infrared detection, and in particular relates to a multilayer stealth nanostructure with a graphene heat conduction layer. Background technique [0002] With the rapid development of electronic information technology and its wide application in the military field, the means of military reconnaissance have achieved high-tech. In the situation where battlefield targets are "hit when found", the advent of infrared imagers has made the once effective visible light and radar stealth technologies face the threat of being cracked. When the atmospheric conditions are good, the airborne infrared search and track system can detect the target at a distance of more than 80km. Therefore, on the basis of visible light and radar band stealth, taking into account infrared is an inevitable trend in the development of full-band stealth technology in the future. [0003] In recent years, the high-precision, intelligent an...
