Outline of Final Research Achievements

1. A new synthesis method, i.e. ammonium-assistant chemical blowing based on a polymeric predecessor, was developed to produce 3D graphenes. The method had high yield (16 wt.%) and low cost (0.25-0.75 US dollar per gram).
2. Based on such 3D graphenes as electrodes of supercapacitors, the supercapacitors achieved high the energy density of 50 Wh/kg at the high maximum-power-density of 340 kW/kg in organic system, which is better than other 3D graphene materials in the same system. In addition, single-crystalline boron nitride nanosheets were produced via a biomass-based carbothermal reduction. They were used for highly thermal conductive insulating polymeric composites.
