▎ 摘　　要

NOVELTY - Preparation of fluorescent thermally reversible self-healing transparent polyurethane composite material involves reacting furfurylamine (FAm) and 4,4'-diphenylmethane diisocyanate (MDI) to produce prepolymer (MPF) by one-step method using dienophile, producing thermally reversible self-healing transparent polyurethane (PU-DA) by DA reaction through electron-withdrawing effect, and adding amino-modified graphene quantum dots before formation of film along the flow through physical bonding. USE - Preparation of fluorescent thermally reversible self-healing transparent polyurethane composite material (claimed) for flexible electronic device. ADVANTAGE - The thermally reversible self-healing transparent polyurethane composite material having excellent light transmittance and fluorescence can be produced.
