Cyclic Voltammetric and Polarographic Study of Conducting Properties of Poly Methyl Aniline (PMA) and its Complex with Zn

Abstract

The development of the field of conducting polymers has continued to accelerate at an unexpectedly rapid rate. in this development there have been contributions from a wide spectrum of scientists such as chemists ,physicists, polymer materials scientists ,spectroscopists, electronic and electrical engineers ,thereby making this field as one of the most interdisciplinary fields of science today . by now these polymers are showing commercial promise in such areas as power equipment , light weight and rechargeable batteries ,micro machines, adhesives and many more applications have been proposed using these exciting systems. In this paper Cyclic Voltammetric parameters and Polarographic parameters for PMA i.e. Poly Methyl Aniline and its Complex formation with Zn have been presented. To find out the number of electrons involved in the electrode process cyclic voltammetric studies have been performed. Sets of solutions containing varying concentration of each of the polymers in 0.1 M potassium chloride (overall concentration) were prepared and the pH was adjusted to 8.0 ± 1 and scan rate was 40 mVs-1 ,similar sets of poly methyl aniline –Zn complex of Various concentration were prepared Cyclic voltammograms of these sets were recorded on the Pulse polarograph CL90 . Fig- 2.2and 2.7 show the cyclic voltammogramms of PMA, Zn –PMA complexes respectively. The cyclic voltammetric data for these species have been tabulated in tables.
