Electrochemical synthesis and characterization of bilayers of poly(O-aminophenol)/ polypyrrole/lignin composites for enhanced charge storage in supercapacitors
2016
Bulletin of the Chemical Society of Ethiopia
Using simple electrosynthesis methods a single and bilayer of conducting polymers, polypyrrole and poly(o-aminophenol) with biopolymer lignin hybrid composites were formed on gold electrodes. The specific capacitance of the single polymer-lignin composite value of 400 F/g obtained from galvanostatic charge-discharge experiment at 1 A/g is improved to a value of 514 F/g in the bilayer polymer-lignin composite systems. The charge capacity is also improved from 61 mAh/g to 121 mAh/g by forming a
