We provide durable perfect blackbody plates with both high emissivity of >0.998 and good heat transfer, ideal for a high-precision reference radiation source. Reflectance measurements and heat transfer simulation demonstrate that a micro-cavity composite of a thin resin double layer or resin mixture with thermally conductive filler is an important solution for improving the emissivity and thermal performance of blackbody plates.}, pages = {4871--4874}, title = {Micro-cavity perfect blackbody composite with good heat transfer towards a flat-plate reference radiation source for thermal imagers}, volume = {46}, year = {2021} }
