An ionically crosslinked conducting polymer poly (3, 4-ethylenedioxythiophene): poly (4-styrenesulfonate) (PEDOT: PSS) hydrogel was synthesized by fast gelation of PEDOT: PSS dispersion (PH1000) using a high concentration of Al³⁺ (2 M) with a high water content of 94.4 wt% and three-dimensional interconnected networks. The highly conductive PEDOT: PSS hydrogel film was achieved by soaking it in ethylene glycol (EG) for a certain time. It was found for the first time that the conductivity of the PEDOT: PSS hydrogel film can be further improved with the vapors of m-cresol. It delivers 158 F g⁻¹ at a scan rate of 50 mV s⁻¹ with an outstanding rate capability and good cycling stability with 84.9% capacitance retention after 2000 cycles.

离子交联的导电聚合物聚（3,4-乙撑二氧噻吩）：聚（4-苯乙烯磺酸盐）（PEDOT：PSS）水凝胶是通过使用高浓度的Al ³⁺（2 M ），水分含量高达94.4 wt％，并具有三维互连网络。高导电性的PEDOT：PSS水凝胶薄膜是通过将其浸泡在乙二醇（EG）中一定时间而制成的。首次发现，间甲酚蒸汽可进一步提高PEDOT：PSS水凝胶膜的电导率。它以50 mV s ^-1的扫描速率提供158 F g ^-1，具有出色的速率能力和良好的循环稳定性，在2000次循环后电容保持率为84.9％。
