Abstract
A novel and simple strategy for one-pot preparation of supramolecular reduced graphene oxide (RGO) hybrid material based on pillar[5]arenes was developed by the redox reaction between graphene oxide (GO) and hydrazide-pillar[5]arene (HP5A, as the reducing agent and stabilizer) in aqueous solution. In this process, no additional reducing agents needed to be added, and no extra modification steps were required after reducing GO. The few-layer RGO-HP5A hybrids fabricated could be dispersed in the water easily and stably. When applied to supercapacitors, this nanocomposite showed a remarkable specific capacitance (331 F
