  • Method of preparing hydrophobic porous silica and hydrophobic porous silica
    Patent number: 11034586
    Abstract: A method of preparing hydrophobic porous silica includes reacting a porous silica particle containing a hydrophilic group in a solvent with an organosilane compound under a basic catalyst to form a mixture, drying the mixture comprising the porous silica particle in a vacuum, and condensation reacting the hydrophilic group of the porous silica particle with the organosilane compound on the surface of the porous silica particle to modify the surface of the porous silica particle to be hydrophobic.
    Type: Grant
    Filed: August 28, 2019
    Date of Patent: June 15, 2021
    Assignee: Research & Business Foundation Sungkyunkwan University
    Inventors: Jae Young Choi, Su Dong Chae, Jang Ho Park, Sung Ho Lee
  • Hydrophobic porous silica and method of preparing hydrophobic porous silica
    Patent number: 10932999
    Abstract: A method of preparing hydrophobic porous silica includes adding an alcohol to a solvent in which a porous silica particle including a hydrophilic group is dispersed and stirring the same to form a mixture, drying the mixture including the porous silica particle in a vacuum, and condensation reacting the hydrophilic group of the porous silica particle with the alcohol on the surface of the porous silica particle to modify the surface of the porous silica particle to be hydrophobic.
