We report a bottom-up molecular engineering strategy to synthesize and integrated 3D nanographenes into carbon nanotube scaffolds for constructing ultrahigh performance hybrid supercapacitors. Strong π–π interactions created a stable hierarchical architecture that enhanced conductivity and suppressed carbon nanotube restacking. Fluorinated nanographene induced polar C–F bonds, boosting cation adsorption and interfacial binding. This study elucidates the critical role of molecular functionalization and provides a rational design strategy for high-performance supercapacitors via precise molecular engineering.

我們發展一種由下而上的有機分子合成，合成並整合三維奈米石墨烯於奈米碳管骨架中，用以構築超高效能的混合式超級電容器。分子間強烈的 π–π 作用力形成穩定的階層式結構，有效提升導電性並抑制奈米碳管的緊密堆疊。除此之外，氟化奈米石墨烯所具備的高極性碳-氟鍵可增強陽離子吸附與界面結合能力。本研究深化有機官能化的關鍵角色，並透過精準的分子合成方法，提供開發高效能超級電容器的合理設計策略。
