Well-controlled electrically conducting rubbers are ideal systems for addressing longstanding questions about intrachain electronic transport mechanisms, intractable for classical conducting polymers except at a very local scale. These doped gels permit observation of macroscopic electromechanical effects, such as changes in strain (τ) upon application of electric fields (see plot), resulting from molecular-scale coupling between transport and chain-conformational properties.
