NOVELTY - A polymer material comprises 70-80 pts. wt. cyclodextrin adamantane-based copolymer, 5-10 pts. wt. modified graphene oxide and 1-3 pts. wt. plasticizer. USE - Polymer material. ADVANTAGE - The polymer material is environmentally-friendly, and has excellent weather resistance, mechanical property and flame retardance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of polymer material, which involves weighing cyclodextrin adamantane-based copolymer, modified graphene oxide and plasticizer, adding weighed material to high-speed mixer and mixing for 25-35 minutes to obtain mixed material, placing the mixed material in a twin-screw extruder, melt extruding and forming.
