Influence of Dopants on Performance of Polypyrrole Coated Carbon Nanotube Electrodes and Devices
Abstract
Polypyrrole (PPy) and PPy-multiwalled carbon nanotube (MWCNT) composites were prepared for charge storage application in electrodes of electrochemical supercapacitors (ES). Chemical polymerization of PPy was performed using 4-amino-5-hydroxynaphthalene-2,7-disulfonic acid monosodium salt hydrate (AHDA) and diamine green black (DAGB) as new anionic dopants. It was found that DAGB improved colloidal stability of MWCNT dispersions and allowed the …
