MWCNTs/V2O5 Nanowire Hetero-junction Actuator Devices
초록/요약
Hetero-junction sheet actuator composed of carbon nanotubes and V2O5 nanowires were demonstrated in a bimetal configuration. The successive filtration of V2O5 nanowire solution followed by carbon nanotube dispersed water solution in the same way produced a dark-gray colored sheet. A significant actuation was observed in sodium chloride electrolyte solution with a bending direction to the carbon nanotube side at the positive bias voltage against the copper counter-electrode. As the frequency of the applied voltage increased, the amplitudes decreased, indicating a rather slow response of the hetero-film actuator in the electrolyte solution. The hybrid structure enabled an easy fabrication of the film actuator with the enhanced efficiencies.
