【 摘 要 】

This work aimedat the synthesis and characterization of particles of modified silica containingthe organic filter dibenzoylmethane (DBM) by the hydrolytic sol-gel method,with modifications to the Stöber route. The structures of the resultingXerogels were characterized by diffuse reflectance UV-VIS spectroscopy in thesolid state, infrared absorption spectroscopy, Scanning Electron Microscopy(SEM) and 29Si Nuclear Magnetic Resonance (29Si NRM).The results showed favorable formation of hybrid organic-inorganic nanoparticleswith efficient absorption/reflectance of radiation in the UV / VIS range, whichenables their potential use as sunscreen.
