<p>A high-sensitivity method of deformation of films of a pyrrole polymer having at least 50 mol % of pyrrole units in air by employing the adsorption and desorption of water and/or a volatile polar solvent on the surface of the film. This method follows a principle different from the conventional one based on stimulus-responsive polymers and enables repeated large deformation and recovery of the film rapidly in air by utilizing minute relative humidity changes of several percent or less. The invention also provides a high-sensitivity method of deformation of pyrrole polymer films functioning also as a high-sensitivity chemical sensor, and enables production of a 'rotary actuator' which moves while rotating, which has been impossible with conventional gels or conductive polymer films, and a 'polypyrrole engine' which is driven by only the vapor of the compound and is expected to act as a novel power source in future.</p> |
