Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation
Advanced Functional Materials, EarlyView.The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.
