▎ 摘　　要

NOVELTY - Nanocomposite material comprises: a dispersed phase; and a continuous phase, where the continuous phase comprises Cyrene (RTM: Dihydrolevoglucosenone). USE - The nanocomposite material is useful for producing a polymer film, a graphene film or a composite film. ADVANTAGE - The nanocomposite material: utilizes the Cyrene (RTM: Dihydrolevoglucosenone) that acts as a continuous medium for producing the material (claimed); and reduces the continuous phase significantly increasing the viscosity of the medium, thus preventing self-association of the dispersed graphene nanomaterial. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the nanocomposite material, comprising preparing a dispersion comprising the dispersed phase and the continuous phase, and evaporating the continuous phase; and (2) a film prepared according to the method.
