Anionic micelles; a new aqueous medium for electropolymerization of poly(3,4-ethylenedioxythiophene) films on Pt electrodes

Development and characterisation of a novel composite electrode material consisting of poly(3,4-ethylenedioxythiophene) including Au nanoparticles

“…Furthermore, massive segregation of SB12 is not observed. The maxima of the main absorption bands are located at 1429 cm −1 , 1515 cm −1 and 1367 cm −1 , associated to symmetric and antisymmetric C C stretching and C ␤ -C ␤ stretching vibrations, respectively [35][36][37][38]. Some additional considerations can be draw out from the spectra: the distribution of the conjugation lengths of the polymer backbone seems to be rather similar in the different materials, since the corresponding ratios between symmetric and antisymmetric C C stretching do not differ significantly [39].…”

Redox behavior and optical response of nanostructured poly(3,4-ethylenedioxythiophene) films grown in a camphorsulfonic acid based micellar solution

“…To address this problem, the use of anionic surfactants was proposed by Sakmeche et al [14] as these form micelles and increase the solubility of the monomer and decrease its oxidation potential. Indeed, the incorporation of an appropriate surfactant in the monomer containing heteroaromatic compounds like PEDOT brings about some drastic changes.…”

Influence of electropolymerization conditions on the morphological and electrical properties of PEDOT film

“…PEDOT film with a smooth and homogenous morphology can be prepared from aqueous sodium dodecylsulfate (SDS) micellar solution with lithium perchlorate (LiClO 4 ) as the supporting electrolyte. In contrast, polymer synthesized from acetonitrile solution containing LiClO 4 has a rough, cauliflower-like structure [8,9]. An electropolymerization process carried out in the presence of SDS at an oxidation potential lower than in a organic medium yields better organized PEDOT films [10].…”
