Electrosynthesis of poly(3,4-ethylenedioxythiophene) (PEDOT) films was performed in a micellar aqueous solution containing sodium dodecyl sulfate (SDS) by cyclic voltammetry, chronoamperometry, and chronopotentiometry on platinum electrode. The electrocatalytic effect SDS characterized significant decrease the EDOT oxidation potential (Ep) medium relative to 0.1 M LiClO4 acetonitrile as well solutions. Linear variation Ep with concentration indicated formation pseudocomplex (Keq = 5.4 × 103...
For the first time, an aqueous micellar medium (sodium dodecyl sulfate, SDS) is used, at Pt electrodes, to electrosynthesize poly(3,4-ethylenedioxythiophene)(PEDOT) conducting films deposited lower potential than in acetonitrile and presenting a well organized structure.
The degradation of five chlorophenoxyacid herbicides has been studied using an electrochemical method based on the Fenton reaction (simultaneous reduction dioxygen and ferric ions). consists electrosynthesizing OH· radicals, which react rapidly with chlorophenoxyacids in aqueous media. HPLC GC-MS analysis show formation polyhydroxyphenols quinones a first step, complete destruction aromatic nucleus upon exhaustive electrolysis. This offers possible way for depollution natural waters...
Highly sensitive multicomponent materials designed for the recognition of hazardous compounds request control over interfacial chemistry. The latter is a key parameter in construction sensing (macro) molecular architectures. In this work, multi-walled carbon nanotubes (CNTs) were deposited on diazonium-modified, flexible indium tin oxide (ITO) electrodes prior to electropolymerization pyrrole. This three-step process, including diazonium electroreduction, deposition CNTs and...
Adhesion of polymers to surfaces is the upmost importance in timely applications such as protective coatings, biomaterials, sensors, new power sources and soft electronics. In this context, work examines role molecular interactions adhesion polypyrrole thin films flexible Indium Tin Oxide (ITO) electrodes grafted with aryl layers from various diazonium salts, namely 4-carboxybenzenediazonium (ITO-CO2H), 4-sulfonicbenzenediazonium (ITO-SO3H), 4-N,N-dimethylbenzenediazonium (ITO-N(CH3)2),...
Abstract To develop conducting organic polymers (COPs) as luminescent sensors for determination of toxic heavy metals, a new benzene sulfonic acid‐doped polypyrrole (PPy‐BSA) thin film was electrochemically prepared by cyclic voltammetry (CV) on flexible indium tin oxide (ITO) electrode in aqueous solution. PPy‐BSA characterized FTIR spectrometry, X‐ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The optical properties were investigated ultraviolet (UV)‐visible...
