AB - An attempt was made to investigate the effect of the preparation temperature on the electrocapacitiveperformance of polypyrrole (PPY)/graphene oxide (GO) nanocomposites (PNCs).
For this purpose, a series of PNCs were prepared at various temperatures by the cetyltrimethylammoniumbromide-assisted dilute-solution polymerization of pyrrole in presence of GO(wt%) ranging from 1.0 to 4.0 with ferric chloride as an oxidant. The formation of the PNCswas ascertained through Fourier-transform infrared spectrometry, X-ray diffraction spectra,scanning electron microscopy and simultaneous thermogravimetric-differential scanningcalorimetry. The electrocapacitive performance of the electrodes derived from sulphonatedpolysulphone-bound PNCs was evaluated through cyclic voltammetry with reference to Ag/AgCl at a scan rate (V/s) ranging from 0.2 and 0.001 in potassium hydroxide (1.0 M). Theincorporation of GO into the PPY matrix at a reduced temperature has a pronounced effecton the electrocapacitive performance of PNCs. Under identical scan rates (0.001 V/s), PNCsprepared at 10 ± 1°C render improved specific conductivity (526.33 F/g) and power density(731.19 W/Kg) values compared to those prepared at 30 ± 1°C (217.69 F/g, 279.43 W/Kg).
PNCs prepared at 10 ± 1°C rendered a capacitive retention rate of ~96% during the first 500cycles. This indicates the excellent cyclic stability of the PNCs prepared at reduced temperaturesfor supercapacitor applications.
