▎ 摘　　要

NOVELTY - Composite material of large area graphene comprises substrate and large-area graphene dispersed in the substrate, where the large-area graphene layer number is less than or equal to 20 layer and has crystallite size (La) diameter of 1-1000 mu meter, and La is obtained by Raman spectroscopy. USE - Composite material of large area graphene. ADVANTAGE - The composite material of large area graphene effectively reduces the needed composite material to reduce the defect generation probability of the composite material.
