Research Progress of Flexible Film Actuator Based on Carbon Nanomaterials
With the development of human-machine interaction,medical and other fields,the traditional rigid actuator has been unable to meet the demand.The flexible film actuator composed of soft materials has attracted wide attention due to its advantages of softness,flexibility and infinite degree of freedom.Sensitive materials that can respond to external stimuli are key components of flexible film actuators.Carbon nano-materials represented by carbon nanotubes and graphene have many excellent properties such as electrical conductivity,thermal conductivity,electrothermal performance,and photothermal performance etc.They have become the most ideal materials for preparing various flexible film actuators and have been widely used in this field.In this paper,based on the research results of flexible film actuators in recent years,the classification and driving mechanism of flexible film actuators are introduced.The application research progress of carbon nanotubes and graphene in various flexible film actuators is summarized.Finally,the future development trend is prospected.
