▎ 摘　　要

NOVELTY - Composite material comprises 25-80 wt.% polymer comprising polypropylene, polyethylene, polystyrene, polypropylene-co-ethylene, polypropylene-co-styrene, polyethylene-co-styrene and/or polypropylene-co-ethylene-co-styrene, 15-70 wt.% lignocellulosic compound, where the lignocellulosic compound is a shive, 2-11 wt.% coupling agent and 0.01-5.5 wt.% graphene. USE - The composite material is used in container, automobile component (claimed), sports articles, appliances, electronic device or consumer goods. ADVANTAGE - The composite material has excellent mechanical properties, improved shrinkage properties, tensile and flexural properties, moisture uptake and heat distortion properties, exhibits improved recyclability and fire retardancy, and reduces environmental impact. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for preparing the composite material comprising (a) mixing the polymer, the lignocellulosic compound, the coupling agent and graphene, and (b) extruding the mixture resulting from step (a).
