Abstract

The class of materials known as conjugated polymers (CP) has attracted great attention due to its optical and semiconductor properties.¹ Among CPs, polyaniline (PANI)² has been found to be a unique material that presents a reversibility character of its conductivity. For example, upon redox and protonation it is possible to change the polymer from an insulating (leucoemeraldine) form, to a conducting polymer (emeraldine salt). Concerning its optical properties, PANI has been attracted interest because of its fast response time.^1,3
