Abstract
In this work, a double-layer radiative coating was designed, and its radiative heat dissipation performance was studied theoretically and experimentally. The duplex coating was fabricated by assembling reduced graphene oxide (rGO) on Al2O3 bottom layer. The effects of Al2O3/rGO coatings on thermal radiation, heat dissipation and anti-corrosion properties of light emitting diode (LED) were investigated. The Al2O3/rGO radiative coating promoted the infrared emissivity value from 0.1 (bare aluminum radiator) to 0.57 at 3
