Figure 6. — (a) Schematic of the working mechanism of SC changes during a negative direction (ND) and positive direction (PD) scan. During the ND scan, P2VP blocks were protonated (P2VP+) and attracted hydrated SO₄^2-. Conversely, the P2VP+ blocks were deprotonated during the PD scan and expelled hydrated SO₄^2-. (b) Photographs of SCs of BCP PC/PANI/ITO device at different potentials during CV cycle in the electrolyte of H₂SO₄-C₂H₅OH-H₂O. Reproduced with permission [11]. Copyright 2021, Wiley-VCH.
