▎ 摘  要

NOVELTY - Preparation of graphene-polyethylene terephthalate (PET) composite fiber comprises activating 20-30 pts. wt. polyester fiber in 75-85 pts. wt. dopamine hydrochloride buffer solution for 25-27 hours, soaking in 90-100 pts. wt. 8.5% graphene oxide aqueous dispersion, stirring for 2-3 hours, taking out, drying to 50-60 degrees C, and repeating process for 5 times to obtain graphene oxide-PET fiber; adding to 70-80 pts. wt. 0.1% hydrazine hydrate ammonia solution, and stirring to 80-90 degrees C for 2.5-3.5 hours. USE - The method is for preparation of graphene-polyethylene terephthalate composite fiber. ADVANTAGE - The method is simple, fast and easy. The composite fiber can be quickly recovered and regenerated, and has good adsorption effect on crystal violet and fast adsorption rate.
