Title: METHOD FOR PREPARING HYDROPHOBIC POROUS SILICA
Abstract:
The present application relates to a method for preparing hydrophobic porous silica, the method comprising the steps of: reacting porous silica particles containing a hydrophilic group in a solvent with an organosilane compound under a basic catalyst; 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 organosilane compound.
