Title:
NEAR-INFRARED SHIELDING MATERIAL MICROPARTICLE DISPERSION, NEAR-INFRARED SHIELDING BODY, COMBINATION STRUCTURE FOR NEAR-INFRARED SHIELDING, AND PRODUCTION METHOD OF THESE
Document Type and Number:
WIPO Patent Application WO/2017/159791
Kind Code:
A1
Abstract:
A near-infrared shielding material microparticle dispersion, a near-infrared shielding body, and a combination structure for near-infrared shielding are provided which contain a composite tungsten oxide that exhibits near-infrared shielding function superior to that of near-infrared shielding material microparticle dispersions, near-infrared shielding bodies, and combination structures for near-infrared shielding that contain conventional tungsten oxides and composite tungsten oxides; also, methods for producing these are provided. This near-infrared shielding material microparticle dispersion comprises near-infrared shielding material microparticles dispersed in a solid medium; the near-infrared shielding material microparticles are composite tungsten oxide microparticles including a hexagonal crystal structure, and as for the a-axis length and the c-axis length of the lattice constant of the composite tungsten oxide microparticles, the a-axis is 7.3850-7.4186 Å and the c-axis lattice constant is 7.5600-7.6240 Å, and the particle diameter of the near-infrared shielding material microparticles is less than or equal to 100 nm.
