The microstructure and infrared emissivity of the coatings were systematically investigated by scanning electron microscopy, infrared emissometer and theoretical simulation. The results show that PU/AlBronze composite coatings have similar one-dimensional photonic structural characteristics. The infrared emissivity of PU/AlBronze composite coatings with composite metal pigments is as low as 0.186 at the pigments content of 40%, and it is significantly lower than that of PU/Al and PU/Bronze composite coatings with single metal pigments. The reasons for this phenomenon are: (1) the reflection spectra of one-dimensional photonic structure in PU/AlBronze composite coatings have multiple reflection peaks; (2) comparing to PU/Bronze composite coatings with high density metal pigments, PU/AlBronze composite coatings have lower thickness of surface resin layer, reducing the emissivity increment of the coatings significantly.
