UV-shielding performance of panoscopically mophology controlled plate-like titanate/calcia-doped ceria nanoparticle composite

Although nanoparticles of semiconductors are used as inorganic UV-shielding materials, the comfort of nanoparticles are modest because of their agglomeration. In order to fabricate UV-shielding materials with better comfort, calcia-doped ceria (Ce_0.8Ca_0.2O_1.8) nanoparticles were coated on plate-like titanate (lepidocrocite type K _0.8Li_0.27Ti_1.73O₄), 10-20μm in diameter. Such panoscopic assembling combined nanoparticles with microparticles successfully improved the comfort of the product when wearing it on the skin without compromising the UV-shielding ability, meanwhile greatly reducing the oxidation catalytic activity, resulting in the fabrication of safe, comfort and high performance UV-shielding material.
