以沉淀烧结法合成 FeCuMnCoO_x粉体，以模板法合成 CuS@Cu₂O复合粉体；采用自制有机硅树脂为粘合剂，以上述粉体为功能填料制备太阳能吸收涂层。采用 XRD和 SEM表征粉体的成分与结构，分别采用紫外可见近红外分光光度计及红外光谱仪测定涂层在 200~2 000 nm和 3 000~2 5 000 nm（中远红外）的光谱反射率，并根据测得的光谱反射率计算涂层太阳能吸收率和发射率。研究 FeCuMnCoO_x粉体中 Co的物相与含量对涂层光谱反射率的影响， FeCuMnCoO_x粉体与 CuS@Cu₂O的配比对涂层太阳能吸收率、发射率及品质因子的影响。结果表明： FeCuMnCoO_x粉体的物相包括（Co，Mn）（Co，Mn）₂O₄、CoFeMnO₄、CuFeMnO₄和 Cu_1.5Mn_1.5O₄。随着 Cu_1.5Mn_1.5O₄和 CuFeMnO₄相的增加， FeCuMnCoO_x -有机硅涂层在 300~1 400 nm的反射率降低，太阳能吸收率（ α_sol）由 92.6%提升至 93.8%。合成的 CuS包覆在规则二十六面体 Cu₂O表面，其粒径为 50~200 nm，光谱反射率（ 200~2 000 nm）低于市售 CuS，不同 CuS/FeCuMnCoO_x复合粉体配比的涂层太阳能吸收率在 91.8%~94.5%，发射率在 17.8%~21.1%。当 m（CuS）∶m（FeCuMnCoO_x）=1∶5时，太阳能吸收率 α_sol=94.5%，发射率 ε_298K=18.2%，品质因子（ α_sol/ε_298K）=5.19，太阳能选择性吸收涂层性能达到最佳。

The FeCuMnCoO_x powder was synthesized by precipitation and sintering process，and the CuS@Cu₂O composite powder was prepared by template method. The solar absorption coatings was prepared by using the home-made silicone resin as the binder and the above powders as the functional fillers. XRD and SEM were used to characterize the composition and structure of the powders. The spectral reflectance of the coatings at 200-2 000 nm and 3 000-25 000 nm（mid-far infrared）was measured by UV-visible near-infrared spectrophotometer and infrared spectrometer，respectively. Ther solar absorptivity and emissivity of the coatings was calculated based on the obtained spectral reflectance. The effects of the phaseand content of Co in FeCuMnCoO_x powder on the spectral reflectance of the coatings，the effects of the ratio of FeCuMnCoO_x powder and CuS@Cu₂O on the solar absorptivity，emissivity and quality factor of the coatings were studied. The results showed that the phase of FeCuMnCoO_x powder included（Co，Mn） ）（Co，Mn）₂O₄、CoFeMnO₄、CuFeMnO₄ and Cu_1.5Mn_1.5O₄. With the increase of Cu_1.5Mn_1.5O₄ and CuFeMnO₄ phases，the reflectivity of FeCuMnCoO_x-silicone coatings decreased at 300-1 400 nm，and the solar absorption rate（αsol） increased from 92.6% to 93.8%. The synthesized CuS was coated on the surface of regular hexahedral Cu₂O， its particle size was 50-300 nm，the spectral reflectance（200-2 000 nm）was lower than that of commercially available CuS，and the coatings with different CuS/FeCuMnCoO_x ratios have a solar absorption rate of 91.8%-94.5%，and an emissivity of 17.8%-21.1%. When the mass ratio of CuS∶FeCuMnCoOx=1∶5，the performance of solar selective absorbing coatings was the best，the solar absorption rate α_sol=94.5%，the emissivity ε_298K=18.2%，and the quality factor（α_sol/ε_{298 K}）=5.19.
