POST-HEATABLE SUBSTRATE

摘要

PURPOSE: A substrate capable of post heat treatment is provided to prevent coherence of thermochromic materials in the post-heat treatment process of the substrate. CONSTITUTION: A substrate capable of post heat treatment comprises a substrate(100), a thermochromic thin film(200), sub-layers(300) and sacrificing layers(400). The thermochromic thin film is formed on the substrate. The sub-layer is formed on the upper and lower surfaces of the thermochromic thin film. The sacrificing layer is formed between the thermochromic thin film and the sub-layer, and is composed of non-oxidized metal. The thermochromic thin film is vanadium dioxide(VO2). The sub-layer is oxide film or nitride film. The non-oxidized metal is one of titanium (Ti), nichrome (NiCr), chrome (Cr), nickel (Ni), aluminum (Al), NB, silicon (Si), zinc (Zn), tin (Sn) or an alloy thereof.
