▎ 摘　　要

NOVELTY - Preparing modified aminoacetic acid graphene oxide comprises (i) using graphene oxide, adding water, ultrasonic dispersing, (ii) using glycine solution, adding step (ii) graphene oxide dispersion liquid, raising temperature to 90-95 degrees C, reacting for 8 -12 hours, separating, drying to obtain the product, where the mass ratio of aminoacetic acid and graphite alkene oxide is 1-5:1. USE - The method is useful for preparing modified aminoacetic acid graphene oxide (claimed). ADVANTAGE - The product has flame retardant effect.
