Supercapacitors are energy storage devices that can be used for hybrid chemical vehicles and power backup supplies. This paper aimed to fabricate polypyrrole-based film electrodes that can be used in such applications. The effect of varying the concentration of sodium p-toluenesulfonate (Na-pTs) used as the dopant in the electrodeposition of the films was also studied.

The film conductivities were determined via Van der Paw Four-Point system. The film thickness at 0.08M, 0.10M, and 0.12M Na-pTs was acquired using SEM analysis and resulted to an average thickness of 24.8 um. the elemental composition of the film electrode was verified by an EDX spectroscopy.

The longest discharging time was 70 minutes obtained from using 0.20M Na-pTs electrolyte concentration. 2014-01-01T08:00:00Z text https://animorepository.dlsu.edu.ph/etd_bachelors/11400 Bachelor's Theses English Animo Repository Physics
