▎ 摘　　要

NOVELTY - Temperature-sensitive and photosensitive composition comprises 20-30 pts. wt. poly(N-isopropylacrylamide)/graphene oxide composite material, 0.5-1 pts. wt. modified vanadium dioxide powder, 1-4 pts. wt. viscosity modifier, 0.05-0.1 pts. wt. rare earth copolymer, 0.1-0.5 pts. wt. antifungal agent, 0.5-1 pts. wt. curing agent, 3-8 pts. wt. solvent and water (balance amount). The poly(N-isopropylacrylamide)/graphene oxide composite material is prepared by emulsion polymerization of graphene oxide after KH570 modification treatment and N-isopropylacrylamide monomer initiated by potassium persulfate; rare earth copolymer is benzenesulfonic acid compound (I). USE - The temperature-sensitive and photosensitive composition is useful for smart windows (claimed). ADVANTAGE - The composition has temperature sensitivity, high light transmittance at low temperatures; can respond to ambient temperature and solar radiation intensity; effectively shield near-infrared light, blocks heat, reduces indoor energy consumption, and maintains the transmittance of visible light at certain range to ensure indoor lighting effects under high temperature or high radiation intensity, stable system, short response time and long service life.
