Abstract

The invention relates to an electric actuation film material and its preparation and application. The electric actuation film material is a graphene oxide / carbon nanotube film. Add carbon nanotubes and surfactants to water, process to obtain carbon nanotube suspension, and vacuum filter to obtain carbon nanotube film; dissolve graphite oxide in water, process to obtain graphene oxide sol, and then scrape coat it on carbon On the nanotube film, drying, repeated scraping and drying, that is to say. The preparation method of the present invention is simple and fast, and can be produced on a large scale. The obtained graphene oxide / carbon nanotube film has rapid, significant and stable electro-deformation properties, and is suitable for use in the fields of flexible electric actuators, mechanical arms and artificial muscles. Has important application value.
