Notes:
Thin films composed of mixtures of metals and dielectric are being considered for use assolar selective coatings for a various applications. By controlling the metal distribution, the solarselective coatings can be designed to have the combined properties of high absorptance, and lowinfrared emittance. We have studied the preparation of the Al-Al2O3 cermet composite filmsdeposited on the flexible Kapton substrate by pulsed direct current (DC) magnetron sputteringtechnique. The complex films include infrared reflective layers, interference absorptive layers, andanti-reflective layers. The measurements of the samples show that the spectral absorptance in theregion of 0.2~2.5μm and thermal emittance in the region of 2.5~25μm were 92% and 7%,respectively
