Ar dielectric barrier discharge jet (DBDjet) plasma treatment of reduced graphene oxide (rGO)–polyaniline (PANI)–chitosan (CS) nanocomposite on carbon cloth for supercapacitor application

Antimony sulfide (Sb2S3) is an emerging photovoltaic material that comprises earth-abundant, non-toxic constituents and has a high absorption coefficient (>104 cm−1). Nevertheless, the serious bulk recombination phenomenon and the slow electrochemical reaction kinetics on the surface of Sb2S3 electrode restrict its application in the photoelectrochemical (PEC) water splitting. Herein, we have designed a polyaniline (PANI)/Sb2S3 p-n junction photoanode successfully to address these issues. With the modification of in-situ anchored PANI, the composite electrode exhibits enhanced light-absorption and accelerated charge transfer efficiency. As a result, the photocurrent density of optimized PANI/Sb2S3 photoanode is about twice of pristine Sb2S3, being a promising material for PEC water splitting.

“…We have previously performed a small jet Ar DBDjet treatment of rGO-PANI-based SCs. 25 A small jet was used to increase the heat dissipation; however, its use greatly increased the scanning time required for the treatment. In this study, in addition to APPJ treatment on carbon cloth, we used low-temperature (<30 °C) helium (He) DBDjet plasma treatment on follow-up screen-printed rGO/PANI/CS nanocomposites.…”

A low-temperature (<30 °C) He dielectric-barrier-discharge jet (DBDjet) is applied to treat screen-printed reduced graphene oxide (rGO)/polyaniline (PANI)/chitosan (CS) nanocomposite flexible gel-electrolyte supercapacitors (SCs) with atmospheric-pressure plasma jet (APPJ)-processed carbon cloth current collectors. The APPJ-treated carbon cloth retained it hydrophilicity for more than 23 weeks. By contrast, carbon cloth furnace-treated at similar temperatures for 30 s and 30 min retained its hydrophilicity for only 6 h and 4 weeks, respectively. Therefore, APPJ treatment benefits the long-term stability of SCs with carbon cloth current collectors. Without substantial heating, the reactive plasma species of the He DBDjet can improve the hydrophilicity of screen-printed rGO/PANI/CS nanocomposites, thereby increasing the SC’s capacitance value. X-ray photoelectron spectroscopy results reveal increased –COOH and C–N contents after He DBDjet treatment, thus explaining the improved hydrophilicity. Galvanostatic charging-discharging measurements demonstrate that the capacitance is improved by 181% after two He DBDjet scans. The capacitance value decreases by only 0.2% after a 10000-cycle CV stability test. No apparent degradation is observed after a 1000-cycle mechanical bending test.
