The effects of dye dopants on the conductivity and optical absorption properties of polypyrrole
journal contribution
posted on 2006-11-01, 00:00 authored by E Håkansson, Tong Lin, Hong Wang, Akif KaynakAkif KaynakTen anionic compounds, including four acidic dyes, were used to dope polypyrrole powder. The effects of the dopants on density, optical absorption and conductivity of the polypyrroles were studied. The presence of the dopant in the conducting polymer matrix was verified by ATR-FTIR spectroscopy. Density function theory (DFT) simulation was used to understand the effect of the dopants on the solid structure, optical absorption and energy band structures. Anthraquinone-2-sulfonic acid-doped polypyrrole yielded the highest conductivity. The dye-doped polypyrrole showed an enhancement in its UV–vis optical absorption.
