. In this system, 00.0 wt% is the CNT fraction that can bring about the maximum number of contacts in the modeled CNT:graphene hybrids. At this concentration, the proportion of graphene-to-CNT contact is the largest (00.0%), followed by CNT-to-CNT (00.0%), and graphene-to-graphene (0.0%) contacts. A synergistic behavior of CNT:graphene hybrids can be observed at this CNT content.
