摘要

In the present study, the spray drying process was used to prepare spherical composite powders from TiO2/mica and h-BN powders. The starting and the as-prepared powders were examined by X-ray diffraction, scanning electron microscopy, particle size analyzer, spectrophotometer, and oil absorption analysis. Particle size distribution, crystalline phases, whiteness, and oil absorption ability were analyzed in order to determine powder morphology. These powders were then mixed into linseed oil to prepare an emulsion for sunscreen protection application. The resultant emulsions were examined using UV-visible-near infra-red (NIR) spectroscopy, sun protection factor tester, and thermal conductivity tester. The experimental results show that spherical composite powder prepared by spray drying not only possess good oil and NIR absorption ability, but also thermal conductivity. The emulsion prepared by spray dried powder exhibits superior sunscreen protection performance compared to its starting counterparts.
