Journal ArticleDOI
Determination of ion populations and solvent content as functions of redox state and pH in polyaniline
Duke Orata,Daniel A. Buttry +1 more
TL;DR: In this article, the piezoelectric quartz crystal microbalance (QCM) is used to investigate the ion populations and solvent content of thin films of polyaniline (PA) on electrode surfaces as functions of redox state and pH.
Journal ArticleDOI
Virtues of composite structures in electrode modification. Preparation and properties of poly (aniline)/nafion composite films
Duke Orata,Daniel A. Buttry +1 more
TL;DR: In this article, the authors used the quartz crystal microbalance (QCM) to identify the ionic species which undergo transport during switching of poly(aniline) between its insulating and conducting forms.
Journal ArticleDOI
Electrodeposition of polyaniline on acidified clay montmorillonite modified electrode
Duke Orata,Fred Segor +1 more
TL;DR: In this article, the authors presented results obtained on derivatization of the working electrode surface with clay montmorillonites treated with varying amounts of acid, and the resultant changes in the population of Bronsted and Lewis acid sites is shown to affect the redox properties of conducting polymer, polyaniline.
Journal ArticleDOI
Bentonite (clay montmorillonite) as a template for electrosynthesis of thyroxine
Fred Segor,Duke Orata +1 more
TL;DR: In this article, a modification of the working electrode surface with clay montmorillonite (bentonite) enhances the iodine redox process and electrosynthesis of thyroxine.
Journal ArticleDOI
A comparative study of the electrochemical/electro-degradation of polyaniline from aniline loaded in a clay-mineral/polyaniline composite matrix to that of the bulk solution
Duke Orata,Stephen Kamau David +1 more
TL;DR: In this article, aniline was trapped in the Bentonite/Polyaniline composite matrix and the rate of polyanilines electrodeposition from this trapped anilines is different from that of the bulk solution.
