Electrochemical impedance spectroscopy as a novel approach to investigate the influence of metal complexes on electrical properties of poly (vinyl alcohol)(PVA) composites
In the current study, black tea leaves extract solution (TES) as a new green technique is used to fabricate metal-polyphenols complexes (X-polyphenols complex; X= Cu+2, Ce+3, and Cd+2). The metal-complexes are integrated with poly (vinyl alcohol) (PVA) to prepare PVA c...

description |
In the current study, black tea leaves extract solution (TES) as a new green technique is used to
fabricate metal-polyphenols complexes (X-polyphenols complex; X= Cu+2, Ce+3, and Cd+2). The
metal-complexes are integrated with poly (vinyl alcohol) (PVA) to prepare PVA composite films. The
electrical properties of pure PVA and composites are characterized using the electrochemical
impedance spectroscopy (EIS) method. The EIS data are fitted to the electrical equivalent circuit to
evaluate the impedance parameters of pure PVA and composite films. The trend of DC conductivity is
further verified by dielectric analysis. The electrical parameters are considerably improved upon
incorporating with the metal-complexes. The effects of the metal-complexes on the modification of
PVA are compared together. The PVA composite incorporated with the Cu+2-complex shows the
highest DC conductivity and dielectric constant, which is important for application in electrochemical
energy storage devices such as batteries and supercapacitors, in comparison with the Ce+3- and Cd+2-
complexes. |
