摘要
The phthalocyanine blue/rutile TiO2 composite pigments were fabricated with a dry ball milling method, and they were characterized by transmission electron microscope (TEM) and fourier transform infrared spectroscopy (FT-IR). The results showed that the hydrophilic/hydrophobic property of rutile TiO2 played a key role on the structure of composite pigment and the phthalocyanine blue (PB) pigment preferred to encapsulate on the surface of hydrophobic rutile TiO2 to form a core-shell structure. And by comparison with the PB pigment, the composite pigment showed 10%-17% higher reflectivity in the wavelength range of 800-1100 and 1200-1600 nm, and the NIR reflectivity in the wavelength range of 1200-1600 nm reached up to 90%.
