Document Type and Number:
WIPO Patent Application WO/2017/212778
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: thermochromic vanadium dioxide-containing particles that have superior storage stability, high thermochromic responsiveness, and thermochromic repetitive durability; a production method therefor; a thermochromic film using said thermochromic vanadium dioxide-containing particles; and a production method therefor. The thermochromic vanadium dioxide-containing particles according to the present invention are each characterized by having a core-shell structure, wherein said core-shell structure has a vanadium dioxide particle in the core, and has, on the surface of the vanadium dioxide particle, (1) a configuration in which a first shell layer A which modifies said surface with an organic compound having at least a hydroxy group and a second shell layer B containing an amorphous metal oxide are formed in this order, or (2) a configuration in which a first shell layer B containing at least one layer of an amorphous metal oxide and a second shell layer B containing a hydrophobic organic compound are formed in this order.
