▎ 摘　　要

NOVELTY - A conductive bio-based plastic comprises 5-55 %mass bio-based material, 15-94 %mass water-insoluble polymer material, and 1-30 %mass two-dimensional material modified with hydrophobic association polymer. USE - Conductive bio-based plastic for electromagnetic shielding (claimed). ADVANTAGE - The conductive bio-based plastic has high strength, and excellent electrical conductivity and electromagnetic shielding property due to excellent compatibility between two-dimensional materials and polymer material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the conductive bio-based plastic, which involves adding hydrophobic association polymer to dispersion of the two-dimensional material, ultrasonically dispersing to obtain two-dimensional material modified by the hydrophobic associationpolymer, and mixing the modified two-dimensional material with dispersion liquid of bio-based material, ultrasonically dispersing, drying, mixing with molten water-insoluble polymer material, and molding.
