Abstract
Provided is a sun protection material including a plurality of polystyrene microspheres and a plurality of refractive layers. The polystyrene microspheres have a particle size of 150 nm to 300 nm. Surfaces of the polystyrene microspheres are at least partially covered by the refractive layers. The sun protection material can scatter a light in a wavelength range between 250 nm and 400 nm. A sun protection composition containing the sun protection material also may scatter a light of a wavelength range between 250 nm and 400 nm, such that the UV protection of the sun protection composition is enhanced.
