 This combination allows the material to have high infrared radiation emittance and high solar reflectivity resulting in effective cooling and heating depending on the orientation of the material. When oriented towards the sun it can provide cooling while when oriented away from the sun it can provide heating. This material can also be used to provide thermal management over a large temperature range as it can be flipped between the two orientations to achieve different results.
