▎ 摘　　要

NOVELTY - Preparation of polyethylene terephthalate-based graphene composite material comprises taking ethylene oxide-modified graphene oxide and polyethylene terephthalate monomer, esterifying, transesterifying, and polycondensation reacting. Polyethylene terephthalate monomer is terephthalic acid and/or dimethyl terephthalate. USE - Method for preparing polyethylene terephthalate-based graphene composite material used for aerostat device (all claimed). ADVANTAGE - The preparation method is simple, short, inexpensive, and suitable for industrial production. The material has improved gas barrier properties and mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for aerostat device comprising polyethylene terephthalate-based graphene composite material gas barrier layer, fiber layer, and weather-resistant layer.
