Abstract (AI)
Mechanically strong and electrically conductive graphene aerogels can be prepared by either supercritical drying or freeze drying of hydrogel precursors synthesized from reduction of graphene oxide with L-ascorbic acid, and the resulting graphene aerogels possess the specific capacitance of 128 F g−1 with superior rate performance.
Key Findings
1
Both supercritical drying and freeze drying processes yield electrically conductive graphene aerogels.
2
Mechanically strong graphene aerogels were prepared from hydrogel precursors synthesized by reducing graphene oxide with L-ascorbic acid.
3
The resulting graphene aerogels exhibit a specific capacitance of 128 F g−1.
4
These graphene aerogels demonstrate superior rate performance when used as electrode materials for electrochemical power sources.
