Title:
METHOD FOR MANUFACTURING LIGHT-SENSITIVE ALL-INORGANIC NANOPARTICLE INK AND 3-DIMENSIONAL STRUCTURE PRINTING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/096028
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a light-sensitive all-inorganic nanoparticle ink and a 3-dimensional structure printing method using same. An aspect of the present invention provides a method for manufacturing a light-sensitive all-inorganic nanoparticle ink, comprising the steps of: preparing nanoparticles capped with an organic material; preparing a nanoparticle dispersion by dispersing the nanoparticles capped with the organic material in a non-polar solvent; preparing an inorganic ligand solution by dissolving an inorganic ligand in a polar solvent; obtaining nanoparticles capped with an inorganic ligand by stirring a mixture in which the nanoparticle dispersion is mixed with the inorganic ligand solution; preparing an all-inorganic nanoparticle solution by dispersing the nanoparticles capped with the inorganic ligand in a polar solvent; and mixing the inorganic nanoparticle solution and a photoacid generator.
