NOVELTY - The composite material comprises a poly(butylene succinate) and graphene oxide. USE - Composite material. ADVANTAGE - The composite material shows good heat resistance, toughness and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite material, which involves: (A) dispersing graphene oxide in water to obtain oxidized graphene dispersion liquid; (B) mixing succinic acid, butanediol and the obtained graphene oxide dispersion liquid by performing esterification reaction; (C) adding titanium catalyst in the obtained liquid after finishing the esterification reaction; and (D) processing condensation polymerization to obtain oxide composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a microscope photograph of an oxidized graphite.
