Electrochemical impedance characterization and potential dependence of poly[3,4-(2,2-dibutylpropylenedioxy)thiophene] nanostructures on single carbon fiber microelectrode

Oligoether Ester-Functionalized ProDOT Copolymers on Si/Monolayer Graphene as Capacitive Thin Film Electrodes

“…42 It was shown that the electrochemical polymerization of the oligo(oxyethylene)-substituted polymer reveals a negative shift of the oxidation potential and a significant enhancement of the effective conjugation length with a 0.10 eV decrease of the bandgap. 43 In addition, carbon-based electrodes electrochemically coated by PProDOTs bearing alkyl and alkyl-aryl groups [44][45][46][47][48][49] or polar functional groups 50,51 show improved capacitive behavior. Recently, PProDOT copolymers carrying oligoether or carboxylic acid functional groups 52,53 were identified for the improvement of the solubility and processability, and were utilized as materials of high capacitance on carbon electrodes.…”

Introducing a redox-active ferrocenyl moiety onto a polythiophene derivative towards high-performance flexible all-solid-state symmetric supercapacitors

“…Similar structures featuring hollow vesicles were also observed with other thiophene-based polymers prepared via the EP technology, and were believed to arise from the oxygen bubbles generated during the electrolysis process of the trace water existing in the untreated commercially purchased reagents. 34–36 As shown in Fig. 2b, the peak C a values of p(FcCPDT)/CC (2.00 F cm −2 ) and p(FcCPDT)/CP (2.97 F cm −2 ) were both observed to be located at 1.3 V vs. Ag/Ag + .…”

Effect of supporting electrolyte on capacitance and morphology of electrodeposited poly(3,4-propylenedioxythiophene) derivatives bearing reactive functional groups

“…A CPE 3 element was introduced in parallel to the R 3 , accounting for the resistance of charges moving between the polymer coating and the glassy carbon. 70 Table S1† presents the change of each parameter as a function of electrolyte type and type of derivative. R 1 varies between 1.58 Ω cm 2 and 10.40 Ω cm 2 depending on the selected derivative and electrolyte.…”

“…In spite of different electrolytes, similar polymeric morphologies appeared with one exception: Bu 4 NBF 4 , LiClO 4 , and Bu 4 NPF 6 produced homogeneous grainy coatings, whereas, with NaClO 4 , a more porous structure was obtained. 69,70…”
