▎ 摘　　要

NOVELTY - The preparation method of a flame-retardant functional cotton fabric based on graphene oxide involves: uniformly mixing diethyl phosphoryl ethyl triethoxysilane, ethanol and deionized water, and violently stirring for 12 hours to obtain a mixed solution; adding graphene oxide and a sandwich type polyacid into the mixed solution, and carrying out ultrasonic treatment for 1-3 hours to obtain a flame-retardant finishing liquid; padding the cleaned cotton fabric in the flame-retardant finishing liquid for 10-20 minutes, and then sequentially drying and baking to obtain the graphene oxide flame-retardant cotton fabric; and soaking the cotton fabric into hydrazine hydrate for reduction reaction, taking out, washing and drying. USE - Preparation method of a flame-retardant functional cotton fabric based on graphene oxide. ADVANTAGE - The flame-retardant functional cotton fabric has high safety, good thermal stability, energy conservation, environmental protection, and high-efficiency flame retardance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the flame-retardant functional cotton fabric.
