▎ 摘 要
NOVELTY - An antenna type graphene nanostructure unit comprises node and antenna shaped nano graphene thin nanoribbon extending outwardly from the node. USE - Antenna type graphene nanostructure unit for use in graphene-based composite material (claimed), electronic devices, sensors, energy storage and other fields. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene-based composite material (2) a method for preparing a graphene-based composite material having topological structure composed of antenna-type graphene nanostructure units.
