Two-dimensional (2D) materials exhibit remarkable properties that suggest many possibilities for electronic applications. Metal organic frameworks (MOFs) are 2D nanosheets materials, which are good candidates for applications in various electrochemical applications such as fuel cells, batteries, and supercapacitors. Herein we report the fabrication of Ni₃(2,3,6,7,10,11-hexaaminotriphenylene)₂ (Ni₃(HITP)₂) flexible all solid-state supercapacitors by electrophoretic deposition (EPD). The Ni₃(HITP)₂ films were electrophoretically deposited in a layer-by-layer fashion onto targeted substrates. The electrodes’ surface morphology characterized by SEM shows a porous surface, and a honeycomb morphology known for improving the capacitive performance. TEM pictures confirmed the ultrathin two-dimensional structure of the (Ni₃ (HITP)₂) electrodes. The electrochemical capacitive performance of the obtained symmetric Ni₃(HITP)₂ supercapacitor has been characterized using cyclic voltammetry measurements and galvanostatic charge-discharge tests. This work demonstrates an exciting potential of EPD for the fabrication of high performance MOFs for flexible solid state energy storage systems.
