“…7, similar selectivity coefficients are obtained for the GC/PGR-MPN/Cd 2+ -ISE and GC/Cd 2+ -ISE, indicating that the selectivity of the proposed ASS-Cd 2+ -ISE is not affected by the solid contact, but is dependent on the sensing membrane itself. These phenomena agree well with those from the reported literatures [45,46].…”

“…Other electrode substrates have been used relatively little, exemplified by gold in an electrochemical quartz-crystal microbalance (ECQM) [8] or glassy carbon [9]; in addition, different assemblies containing PEDOT obtained in combination with carbon nanotubes [10] or carbon nanofibres [11] have also been reported. PEDOT has been applied to the detection of several important chemically and biologically relevant compounds such as hydrogen peroxide [12,13], nitric oxide [14], dopamine [9] and ascorbic acid [15].…”

Characterisation of the modified electrodes was done by cyclic voltammetry and electrochemical impedance spectroscopy and the stability of the polymer films was probed. The coated electrodes were tested for application as hydrogen peroxide sensors, by oxidation and reduction. A novel polymer film was also formed by modification of CFE by co-electropolymerisation of EDOT and the phenazine dye neutral red (NR) -(PEDOT/PNR) with a view to enhancing the properties for sensor applications. It was found that hydrogen peroxide reduction at the PEDOT/PNR coated electrodes could be carried out at a less negative potential, the sensor performance comparing very favourably with that of other polymer-modified electrodes reported in the literature.

“…Better stability of the (p)N-CNTs/pEDOT/PSS nanocomposite electrode layer is probably due to improved mechanical properties caused by the presence of plasma treated carbon nanotubes. 80 Chronopotentiometric curves recorded at different currents (inset in Fig. 9) are symmetrical, conrming fast and reversible charge-discharge processes of investigated nanocomposite electrode layers.…”

High-performance method of carbon nanotubes modification by microwave plasma for thin composite films preparation

In this work we present a simple and efficient method of nitrogen plasma modification of carbon nanotubes (CNTs). The process allows for treatment of the nanotubes in the form of powder with quite a high yield (65 mg of CNTs per hour). The modified carbon nanotubes contain approx. 3.8% nitrogen, mostly in the pyridinic form. Plasma treated CNTs exhibit better dispersibility in water and higher electric capacitance than pristine CNTs. Modified CNTs are a proper component of novel nanocomposites based on the conducting polymer poly(3,4-ethyleneidoxythiophene). Electrodeposited thin layers of the nanocomposite exhibit improved electrochemical properties (higher capacitance, better stability, lower resistance, faster diffusion) compared to the pure polymer layers.
