Abstract

By electrochemical stimulation of conformational changes along a chain of a conjugated polymer a molecular muscle is obtained. The electrochemically stimulated conformational relaxation model allows a good theoretical description of the electrochemical chronoamperograms, voltammograms or chronocoulograms performed under influence of different chemical or physical variables. Electrochemical and structural magnitudes were integrated in the same model. Through a geometrical model three dimensional processes (change of volume) occurring in polymeric films were transformed in one dimensional change, describing bilayer effects, angles described by a bilayer muscle and angular movements as a function of the current flowing by the device. Being the current a function of both, electrochemical and structural magnitudes, angular movements can be described as a function of then.
