  • Method for manufacturing hybrid packaging material
    Patent number: 10294378
    Abstract: Disclosed herein is a method of manufacturing a hybrid packaging material, comprising the steps of: (a) forming a colloidal inorganic nanosol; (b) surface-treating the inorganic nanosol of step (a) with an organic metal alkoxide containing an organic function group by stirring the inorganic nanosol together with the organic metal alkoxide; (c) replacing a solvent of the inorganic nanosol with an organic solvent different in type from the solvent to prepare an organic solvent-type inorganic nanosol; (d) substituting the organic solvent of the inorganic nanosol of step (c) with a functional organic monomer or a silicon compound, followed by concentration to prepare a solvent-free organic-inorganic hybrid material; and (e) adding a nanoclay dispersed in a solvent to the solvent-free organic-inorganic hybrid material.
    Type: Grant

    Date of Patent: May 21, 2019
    Assignee: Korea Electrotechnology Research Institute
    Inventors: Dong-jun Kang, Hoy-yul Park, Myeong-sang Ahn
