“…The stretchable SC achieved mass and areal capacitance of 18.55 F g À1 and 53 mF cm À2 at a current of 0.07 mA and presented rate performance with 68% retention of its original capacitance when the current was enhanced to 3.5 mA (Figure 6(f)). Due to the electrode substrate having diamond-shaped loops, the areal capacitance of the assembled device is lower than some in the literature, including polyaniline (PANI)/graphene composite (72.3 F g À1 at 1 A g À1 ) 42 and PEDOT:polystyrene sulfonate (PSS)/ multi-walled carbon nanotube (MWCNT) film (20.3 F g À1 at 1 mA), 43 but still higher than some SCs, such as graphene hydrogel/Zn foils (33.8 mF cm À2 at 1 mA cm À2 ), 44 ZnO-MnO 2 -carbon cloths (26 mF cm À2 at 0.5 mA cm À2 ), 45 activated carbon cloths (31 mF cm À2 at 10 mV s À1 ), 46 metal organic framework (MOF)/PANI/carbon cloth (35 mF cm À2 at 0.05 mA cm À2 ) 47 and RGO-PANI (39.08 mF cm À2 at 1 mA), 48 which is summarized in Table 1. Moreover, the as-prepared device retained %73% of its original capacitance after 5000 cycles (Figure 6(g)).…”

“…The rGO/PANI pastes were then screen-printed onto an APPJ-modified graphite sheet with an area of 2.0 cm × 1.5 cm. After the screen-printing process, it was annealed at 100 • C for the duration of 10 min as the electrode of supercapacitors [11]. Polyethylene terephthalate (PET) was used to fix the electrode.…”

“…The preparation of PANI nanocomposites combining with various materials has been developed to reduce the disadvantage. Graphene, a two-dimensional material, has the properties of ultra-high specific surface area, good electrical and thermal conductivity as well as excellent mechanical properties [8,9]; therefore, graphene and its derivatives have been applied in supercapacitors [10,11]. Specific capacitance in the value of 550 F/g could be realized theoretically if their surface area can be completely used.…”

“…[ 254–256 ] Low‐temperature post‐processing techniques compatible with thermal‐sensitive flexible substrates, such as thermal annealing (e.g., <250 °C), microwave annealing, deep ultraviolet radiation (DUV), and high‐pressure annealing, have been applied to anneal printed functional materials, including metallic nanomaterials, metal oxides (e.g., metal–oxide dielectrics and semiconductors), 2D materials, organic and organic–inorganic hybrid semiconductors, etc. [ 257–262 ] Generally, organic impurities in the printed patterns, such as residual solvents, surfactants, and additives, etc., could be healed during the post‐processing procedure, which improves the mechanical and/or electrical performance of the printed functional patterns due to the enhanced particle–particle interactions. [ 182,251 ] For example, the removal of residual solvents or surfactants in printed 2D materials could enhance particle–particle interactions.…”
