HYDROTHERMALLY STABLE MESOPOROUS ETHANE-SILICA AND THE PREPARATION METHOD THEREOF

摘要

The present invention relates to mesoporous ethane silica having excellent hydrothermal stability, and more particularly, to PEO-PLGA-PEO (ethylene oxide) -b-Poly (lactic acid-ran-glycolic acid) -b- Preparing an aqueous solution comprising a poly (ethylene oxide) block copolymer and an acid; Preparing a reactant by mixing an ethane silica precursor with the aqueous solution; And hydrothermally synthesizing the reactant; wherein the acid includes a weak acid having a pKa of 2.2 or less, and relates to a process for preparing ethane silica and ethane silica prepared therefrom.
