| description | This study describes nanoparticle pigmented coatings used in controlling the radiative properties of surfaces exposed to sunlight. The effect of particle dispersed state to reflectance of the coating is discussed. As the dispersed particles, TiO2 and Fe2O3 are used. From Raman spectral intensity measurements made on the coating, the dispersed state of particles was investigated. The spectral reflectance of the coating was measured by spectroscopy. The reflectivity of the coating is analyzed theoretically. In this calculation, the dispersed state is assumed to be monodispersed and homogeneous. Comparison between experimental and numerical results shows that the difference between the measured and calculated reflectance increases as the volume fraction increases. The maximum absolute error of reflectance is about 10% when the volume fraction is 0.05. In contrast, the maximum absolute error of reflectance is about 3% when the volume fraction is 0.01. The control of dispersed state affects the radiative properties of pigmented coatings. |
