▎ 摘　　要

NOVELTY - A polylactic acid/nanocellulose whisker/graphene oxide ternary composite material comprises polylactic acid, nanocellulose whiskers, graphene oxide, and a coupling agent. USE - Polylactic acid/nanocellulose whisker/graphene oxide ternary composite material. ADVANTAGE - The polylactic acid/nanocellulose whisker/graphene oxide ternary composite material is environmentally-friendly. Using blending combination of nanocellulose whiskers and graphene oxide as reinforcements for toughening and modifying polylactic acid, in order to simultaneously solve the defect of poor toughness of polylactic acid, retain the advantage of easy degradation of polylactic acid, and improve the environmental protection of composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite material, which involves dissolving polylactic acid in an organic solvent, stirring, adding nanocellulose whiskers, graphene oxide and coupling agent, ultrasonically-dispersing, and drying in vacuum.
