Title: HYDROPHOBIC POROUS SILICA AND PREPARATION METHOD THEREFOR
Abstract:
The present application relates to a preparation method for hydrophobic porous silica, the method comprising the steps of: adding an alcohol to a solvent in which porous silica particles containing a hydrophilic group are dispersed, followed by stirring; and drying the porous silica particles in a vacuum state, wherein a surface of the porous silica particle is hydrophobically modified by a condensation reaction of a hydrophilic group of the porous silica particle and the alcohol.
