The padding roller was set at a speed of 1m/ min with a pressure of 0.74 bar. The padded fabrics were subsequently dried at 100°C for 5 min at a Mini Thermo Oven, Type 350 Special (Roaches, UK). Several coated samples were prepared using multiple (1-10) padding passes to establish any improvement in the electrical conductivity of the coated fabrics. We further optimized the curing temperature and time using a range of curing temperatures (110°C-160°C with 10°C intervals) over a time range (5-15 minutes with 5-minute intervals). We used the optimized coating parameter and curing condition to further produce supercapacitor electrode.
