We report the synthesis of composite RuO2/(3,4-ethylenedioxythiophene) (PEDOT) nanotubes with high specific capacitance and fast charging/discharging capability as well as their potential application to the electrode materials for a high-energized and high-powered supercapacitor. We show that the energy density (specific capacitance) of PEDOT nanotubes can be remarkably enhanced by electrodepos...

An in vitro comparison of conducting-polymer nanotubes of poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(pyrrole) (PPy) and to their film counterparts is reported. Impedance, charge-capacity density (CCD), tendency towards delamination, and neurite outgrowth are compared. For the same deposition charge density, PPy films and nanotubes grow relatively faster vertically, while PEDOT films and ...

The present study describes the preparation and electrochemical characterization of poly(bisphenol A) (poly(BPA)) supported poly(3,4-ethylenedioxythiophene) (PEDOT) modified gold electrodes. Cyclic voltammetry (CV) impedance spectroscopy (EIS) were used to characterize electrochemistry Au | PEDOT 0.1 mol/dm3 H2SO4(aq.) [poly(BPA)/PEDOT] electrodes before after overoxidation. Scanning electron m...

Heavy metal ion pollution has had a serious influence on human health and the environment. Therefore, monitoring of heavy ions is great practical significance. In this work, we describe development an electrochemical sensor to detect cadmium (Cd2+) using Prussian blue (PB), poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT)-loaded laser-scribed graphene (LSG) nanocomposite-modified ...

The conducting polymer PEDOT (poly-3,4-ethylenedioxythiophene) has been polymerized onto 3 mm and 10 μm electrodes from a propylene carbonate solution. The electrodes have then been tested in a Chardonnay wine, including dilutions in a model wine solution, with comparisons made to scans with a glassy carbon electrode. A well-defined oxidation peak was obtained for the white wine at PEDOT in the...

Obtaining modified electrodes is a response of electrochemistry to continuous development in areas such as technology, electronics, medicine, biology and many others. Modifying layers allow scientists to build electrodes with required properties such as for example: selectivity, stability, precision, durability, range of potentials etc. The aim of the studies was to modify the surface of gold a...

Chemically synthesized layered manganese dioxide ( δ -MnO 2 ) modified by poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) dispersion were used as cathode materials for aqueous Zn-ion batteries (AZIBs). A comparative study of electrochemical properties cathodes with pristine MnO chemically conducting polymers in different forms was ...

OBJECTIVE The aim of this study was to compare two different microelectrode materials--the conductive polymer composite poly-3,4-ethylenedioxythiophene (PEDOT)-carbon nanotube(CNT) and titanium nitride (TiN)--at activating spikes in retinal ganglion cells in whole mount rat retina through stimulation of the local retinal network. Stimulation efficacy of the microelectrodes was analyzed by compa...
