The MOF inkjet-printed textiles were then utilized as electrodes for inkjet-printed symmetric textile supercapacitor application. Similar to the previous supercapacitors, a two-electrode system was used to investigate the electrochemical performances of the sandwiched-shaped supercapacitor. Keeping a similar trend, the ink-jet printed supercapacitor also exhibited battery-shaped CV curves (Figure ) at various scan rates, indicating ideal pseudocapacitive behaviour. The supercapacitor exhibited an areal capacitance of ~353.5 mFcm -2 and a gravimetric capacitance of 86.64 Fg -1 at a scan rate of 1 mVs -1 at the same voltage windows (-1.0V to 1.0V). It is to note here that, the inkjet-printed supercapacitor exhibited areal capacitance almost nearer to the coating process but was very high (⁓86.64 Fg -1 ) compared to both screen-printed (⁓12.88 Fg -1 ) and coated supercapacitor (⁓24.62 Fg -1 ). The phenomenon could be attributed to the composition of our water-based inkjet printing ink. The water-based ink is mostly composed of water which after drying and curing gets evaporated leaving only the active MOF particles, which results in higher gravimetric capacitance. Though only a very small amount of additional material (binder, viscosity modifier and surface tension modifier) is present in the inkjet printable ink, that does not affect significantly as surfactant of coating solution or thickener of screen-printing ink for capacitance. Figure represents a comparison of the areal and gravimetric capacitance of the supercapacitor at various scan rates.
