The fabrication of conical nanocarbon structures (CNCSs) on a transparent and flexible nafion substrate at room temperature using an ion irradiation technique and their application toward field emission displays (FEDs) have been demonstrated. The main advantage of this technique is that CNCSs can be fabricated directly on the transparent substrate while retaining the transparency of the substra...

The electrochemical performance of single wall carbon nanotube ~SWNT!/Nafion composite electrodes were studied in sulfuric acid solutions. Electrochemical oxidation of the highly dispersed SWNTs within the Nafion matrix results in a dramatic morphological change in the SWNTs. As evidenced by transmission electron microscopy, small bundles of straight-line SWNTs change into curved bundles with r...

Polymer electrolyte membranes have found broad application in a number of processes, being fuel cells, due to energy concerns, the main focus of the scientific community worldwide. Relatively little attention has been paid to the use of these materials in electrochemical production and separation processes. In this review, we put emphasis upon the application of Nafion membranes in electrochemi...

A new outer layer composition, consisting of polytetrafluoroethylene (PTFE), Kel-F oil, and Nafion, is suggested to minimize the detrimental effect of dissolved oxygen and to extend the linear response range of a glucose oxidase(GOx)-based sensor using nonconducting polymer. The morphology of Kel-F/PTFE/Kel-F/Nafion polymeric laminate was followed during fabrication by SEM. When Kel-F film was ...

An embedded silica optical microfiber knot resonator humidity sensor is presented. As silica has a poor response to environmental humidity changes, a surrounding layer of Nafion is used as a transducer. Spectral characterization and also a procedure to determine the coupling and total loss coefficients are presented. Sensitivity as high as (0.29±0.01)  nm/% relative humidity has been noticed. P...

Reversed-phase membrane inlet mass spectrometry incorporating a hollow-fiber Nafion membrane has been evaluated for the determination of low molecular weight alcohols in chloroform. The hydrophilic Nafion membrane preferentially transports methanol and ethanol, allowing percentage concentrations of the alcohols to be determined in a chloroform matrix. A linear response was observed for ethanol ...

The voltammetric behaviour of methylmercury at Nafion coated glassy carbon electrodes is examined. Cyclic voltammograms recorded at coated electrodes show a dramatic increase of peak currents with respect to bare electrodes, this effect being more evident in perchlorate supporting electrolytes rather than in chloride containing media. Experimental evidence indicates that ion-exchange preconcent...

In the present study, Composite materials based on perfluorinated cation-exchange membrane incorporating particles of Zirconium and Nafion is synthesized .With this membrane the performance of the electrolysis cell improved considerably at room temperature and atmospheric pressure. In addition, by using catalysts and membranes, the performance of this Composite membrane is studied by varying vo...
