Optimum Fullerenol Concentration for Actuation of Polyurethane Elastomer Film

摘要

Polyurethane elastomer film attracts much attention for the application of soft actuator. We are developing the fascinating actuator by the improvement of bending displacement. We have vaired the doping content of fullerenol during the forming process. We found that the doping or fullerenol enhances the bending displacement with the applied voltage, but that too much doping does not show the enhancement. The optimum concentration of fullerenol was found to be 0.25%.
