Abstract
Periodic nanostructures for high energy-density and high-power density device and systems and uses thereof. Hierarchical nanostructured materials having stacked polymer nanowires forests interconnected by monolayer graphene sheets were fabricated through bottom-up nanofabrication. Driven by external voltage, aniline molecules and graphene oxide were alternatively assembled for hierarchical porous stacked nanostructures while graphene oxide was in-situ reduced to graphene during the assembly process. As-produced hierarchical nanostructures can be used as supercapacitor electrodes, which can utilize the discovered stack-dependent device properties.
