▎ 摘　　要

NOVELTY - Weather-resistant electrochromic paint comprises 40-50 pts. wt. amino-terminated hyperbranched polyurethane, 10-20 pts. wt. epoxy functional copolymer, 15-25 pts. wt. liquid crystal material, 0.1-0.5 pts. wt. conductive material, 0.1-0.3 pts. wt. coupling agent, 4-7 pts. wt. ionic liquid and 10-15 pts. wt. organic solvent. The epoxy functional copolymer comprises units formed from the following monomers radical polymerizable fluorine-containing liquid crystal compound, silicon fluorene containing ethylenically unsaturated bonds, sulfobetaine monomers containing ethylenically unsaturated bonds and other monomers containing ethylenically unsaturated bonds and epoxy groups. USE - The weather-resistant electrochromic paint is useful in high-grade hotel, museum, conference office, bank, commercial window and automobile window. ADVANTAGE - The weather-resistant electrochromic paint has good performance stability, sufficient weather resistance, and obvious electrochromic effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing weather-resistant electrochromic paint, comprising mixing 40-50 pts. wt. amino-terminated hyperbranched polyurethane, 10-20 pts. wt. epoxy functional copolymer, 15-25 pts. wt. liquid crystal material, 0.1-0.5 pts. wt. conductive material, 0.1-0.3 pts. wt. coupling agent, 4-7 pts. wt. ionic liquid and 10-15 pts. wt. organic solvent and dispersing uniformly under ultrasonic condition.
