“…33 The XPS spectra of O 1s also contain peaks at 531.4 eV, 532.3 eV, and 534.3 eV that can be accredited to C–O–C, SO, and S–O in PEDOT. 31 The carbonyl oxygen atom and COOH bond associated with MMA can be confirmed from less intense peaks obtained at 530.7 eV, 531.0 eV, and 532.0 eV. 34 The C 1s XPS spectrum showcases various peaks at 283.7 eV, 284.0 eV, and 285.3 eV indicating the overall enhancement of C–C or CC bonds associated with carbon.…”
