ABSTRACT

Biomimetic actuators that can produce soft-actuation but large force capability are of interest. Nafion, an effective ionomeric material from DuPont, has been shown to produce large deformation under low electric fields (<10V/ mm). Carbon nanotube/polymer nanocomposites were cast to enhance the electromechanical properties of the composites. Multiwalled carbon nanotube (M-CNT)/Nafion nanocomposites were prepared by a solution casting to investigate the effect of M-CNT loading in the range of 0 to 7wt% on electromechanical properties of the M-CNT/Nafion nanocomposites. The measured elastic modulus and actuation force of the M-CNT/Nafion nanocomposites are drastically different, showing larger elastic modulus and improved electromechanical coupling, from the one without M-CNT.
