NOVELTY - A polymer nanocomposite material comprises a filler including graphene oxide-cyclodextrin (I). USE - Polymer nanocomposite material (claimed). ADVANTAGE - The polymer nanocomposite material is efficiently prepared by simple process. DETAILED DESCRIPTION - A polymer nanocomposite material comprises a filler including graphene oxide-cyclodextrin of formula (I). X=cyclodextrin of formula (II);and n=6, 7 or 8. An INDEPENDENT CLAIM is included for preparation of polymer nanocomposite material, which involves preparing graphite oxide solid using natural crystalline flake graphite powder, preparing graphene oxide dimethylformamide suspension using graphite oxide solid, in which the content of graphite with respect to dimethylformamide is 7.5-15 mg/mL, preparing chlorinated graphene oxide using graphene oxide dimethylformamide suspension, preparing dimethylformamide solution of cyclodextrin, in which the content of cyclodextrin with respect to dimethylformamide is 2-500 mg/mL, adding chlorinated graphene oxide to resulting solution, heat-stirring, filtering, washing and drying to obtain graphene oxide-cyclodextrin-based hybrid material, preparing polymer solution using 0.05-1 g/mL polymer and solvent, dispersing hybrid material into solvent, adding resulting solution to polymer solution, stirring, and volatilizing the solvent.
