Abstract
(EN)
A graphene-based conductive structure having a self-repairing function, a manufacturing method for the same, and a self-repairing method for a graphene-based conductive structure having a self-repairing function. The graphene-based conductive structure having a self-repairing function comprises graphene nanosheets and nanocellulose. The graphene-based conductive structure having a self-repairing function has both high mechanical strength and superior electrical conductivity, is capable of restoring its shape and electrical conductivity in an aqueous environment after breakage, has high flexibility, and is widely applicable in fields such as high-performance fibers, biosensors, composite fiber materials, and adsorbent materials.
