| 英文摘要 | Transparent inorganic uv-filter/epoxy nanocomposites with high photo-stabilization properties were reported in this paper. first, inorganic uv-filter zno, core-shell structural silica-titania (s-t) and silica-titania-silica (s-t-s) nanoparticles were synthesized. transparent inorganic uv-filter/epoxy (zno/epoxy, s-t/epoxy and s-t-s/epoxy) nanocomposites were subsequently prepared from the transparent epoxy and the as-prepared nanoparticles via in situ polymerization method. optical properties of inorganic uv-filter/epoxy nanocomposites, namely visible light transparency and uv-light shielding efficiency, were studied using an uv-vis spectrophotometer. the photo-stabilization properties of inorganic uv-filter/epoxy nanocomposites were examined by the light-emitting diode (led) lifetime test. the results showed that the photo-stabilization effect of inorganic uv-filter on the lifetime of led lamp obeys the following sequence: zno > s-t-s > s-t. compared with the uv led lamps encapsulated with pure epoxy, the lifetime of uv led lamps encapsulated with zno/epoxy, s-t-s/epoxy and s-t/epoxy nanocomposites has been improved by 76%, 54% and 33%, respectively.
