▎ 摘　　要

NOVELTY - Preparing intelligent color-changing liquid crystal fabric comprises (i) preparing dopamine hydrochloride modified fabric, (ii) preparing the graphene oxide nanosheet stable dispersion and polydiene dimethyl ammonium chloride solution dispersed by phytic acid, soaking the dopamine hydrochloride modified fabric into the graphene oxide nanosheet stable dispersion and polydiene dimethyl ammonium chloride solution dispersed in phytic acid, self-assembling the surface of the dopamine hydrochloride modified fabric to construct light/electric/heat conversion layer, obtaining the modified substrate, and (iii) preparing thermochromic paint by cholesteric liquid crystal microcapsule, coating the thermochromic paint on the surface of the modified substrate to obtain the intelligent color-changing liquid crystal fabric. USE - The fabric is useful in military protective concealment materials, flexible displays, anti-counterfeiting signs or safety warnings or artistic ornaments (claimed). ADVANTAGE - The fabric: can be irreversible discoloration under the electric field, infrared light and temperature stimulation; has bright and variable color; is sensitive in response; and has excellent solvent resistance and water resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for intelligent color-changing liquid crystal fabric prepared by performing the above-mentioned method.
