Free-standing two-dimensional (2D) porous nanomaterials have attracted considerable interest as ideal candidates of 2D film electrodes for planar energy storage devices. Nevertheless, the construction of well-defined mesopore arrays parallel to the lateral surface, which facilitate fast in-plane ionic diffusion, has remained a great challenge. Herein, we demonstrate for the first time, a universal interface self-assembly strategy for patterning 2D porous polymers, e.g. polypyrrole, polyaniline and polydopamine, with cylindrical mesopores on graphene nanosheets. The resultant 2D sandwich-structured nanohybrids are employed as the interdigital microelectrodes for the assembly of planar micro-supercapacitors (MSCs), which deliver outstanding volumetric capacitance of 102 F cm-3 and energy density of 2.3 mWh cm-3, outperforming most reported MSCs. Further, the MSCs display remarkable flexibility and superior integration for boosting output voltage and capacitance. The interfacial self-assembly protocol opens novel opportunities for patterning 2D mesoporous nanosheets for planar energy storage devices.
