摘要：
Polyurethane (PU) /bronze-Sm2O3 composite coatings were prepared through a simple and convenient process by using bronze-Sm2O3 as the pigments and PU as the adhesives, respectively. The infrared emissivity, near-infrared absorption property, and mechanical properties of as-prepared coatings were systematically investigated. The results indicate that the existence of Sm2O3 can obviously decrease the near-infrared light reflectivities at 1.06μ m and 1.54 μm, the existence of bronze powders can effectively reduce the infrared emissivity at the wavelength of 8-14 μm. By adjusting the mass ratio of bronze to Sm2O3, the infrared emissivity at the wavelength of 8-14 μm can be tuned from 0.422 to 0.782, and the reflectivities at 1.06 μm and 1.54 μm can be tuned from 46.8% to 65.0% and 49.3% to 70.7%, respectively. In addition, the coatings have good mechanical properties, the adhesion and impact strength of the coatings with different mass ratios of bronze to Sm2O3 can reach grade 1 and 50 kg·cm, respectively. © 2016, Beijing Institute of Aeronautical Materials (BIAM).
