제목 Preparation of melanoidin/TiO2 composites with improved UV screening ability
초록 Melanoidin/TiO2 composites were prepared to enhanced UV blocking ability. TiO2 microspheres were synthesized through surfactant-assisted sol-gel method followed by carboxylation on TiO2 surface to introduce chemical binder. Then, dihydroxyacetone (DHA) was grafted on TiO2 by esterification between carboxyl groups of TiO2 and hydroxyl groups of DHA. The melanoidin/TiO2 composites were obtained by the Maillard reaction between DHA/TiO2 and arginine. The synthesized melanoidin/TiO2 composites provided the broad range of UV protection properties from 280 nm to 400 nm and reduced intrinsic white cast phenomena of TiO2 by exhibiting brown color. It is expected that the hybrid composites can be applied in cosmetic field.
