Among several methodologies to improve the solution processing of graphene-based materials, noncovalent
functionalization has been considered as the simplest and nondestructive method. Herein, we show that molecular selfassembly process can be used as a useful tool to exfoliate reduced graphene oxide (RGO), resulting in hybrid materials with improved physical properties. Upon interacting with a π-gelator, the dispersing ability of the RGO increased significantly in most of nonpolar and polar aprotic solvents when compared to the bare one. The amount of RGO dispersed was 1.7−1.8 mg mL−1 in solvents such as toluene, odichlorobenzene
(ODCB) and tetrahydrofuran (THF). Morphological studies revealed that aggregation of π-gelator over RGO helps to exfoliate graphene layers to remain as individual sheets with higher surface area. Experimental studies revealed enhanced surface area (250 m2 g−1) and better conductivity (3.7 S m−1) of the hybrid materials with 30% of RGO content resulting in excellent electrochemical performance (specific capacitance of 181 F g−1) as electrodes for supercapacitors. |
