- flexible actuator manufacturing method with carbon nanotube-graphene tube material applied

摘要

The present invention relates to a method for manufacturing a flexible actuator applied with carbon nanotube (CNT)-graphene tube material, which comprises a first step of synthesizing a metal catalyst in a nanowire form, and producing the same in a powder form; a second step of growing graphene on the surface of the metal nanowire through chemical vapor deposition, and further growing CNT through the chemical vapor deposition by spraying metal catalyst particles on the surface thereof; a third step of removing the metal nanowire to produce a CNT-graphene tube form; a fourth step of performing a casting process by adding the CNT-graphene tube to an ionic polymer solution to produce a film in which the CNT-graphene tube and the ionic polymer are mixed; and a fifth step of attaching CNT-graphene tube electrodes on both sides of the film, in which the CNT-graphene tube and the ionic polymer are mixed, to finally produce an electroactive polymer flexible actuator added with the CNT-graphene tube material. According to the present invention, an effective driving characteristic as an electrode of a driver can be provided by improving an electron transmission characteristic.
