Phosphate Buffered Saline

ABSTRACTA variety of materials have been evaluated for use as electrodes for neural stimulation. In an effort to maximize the charge density on the electrode surface, faradaic stimulation electrodes have been investigated. Electrodes consisting of thin films of polypyrrole on Pt have been studied in phosphate buffered saline using cyclic voltammetry at 100 mV/s. The electrode capacity diminishes initially but stabilizes after ˜500 cycles. The electrodes were further evaluated in pulsing experiments using constant current, biphasic pulses. In these experiments, significant charge storage was observed only when using pulse widths greater than 5 ms. A modified polypyrrole was prepared using anthraquinone containing electrolyte. This new material is an apparent improvement over the polypyrrole previously studied.

Pulse cathodic electrodeposition of manganese oxide was performed from 0.005M MnCl2 in the presence of cetyl trimethylammonium bromide (CTAB). The electrosynthesis experiments were done at the simple pulse mode (ton=1ms and toff=1ms) with applying current density of 10 mA cm–2. The structural analyses through XRD and FTIR revealed that the prepared sample have the pure hausmannite crystal structure. Morphological observations by SEM showed that the deposited hausmannite has mixed rod/particle morphology. The charge storage performances of the prepared hausmannite were evaluated by cyclic voltammetry and charge-discharge techniques. The Mn3O4 working electrode exhibited only 13% capacity decay after 1000 cycles at the current load of 2 A g–1, and its SC value reduced from 239 F g–1 to 207 F g–1. The results proved that the prepared Mn3O4 nano-rods/particles are suitable electrode material for supercapacitors.
