Title:
METHOD FOR PRODUCING METAL NANOCOIL
Document Type and Number:
WIPO Patent Application WO/2016/129589
Kind Code:
A1
Abstract:
Provided is a method for producing a metal nanocoil, which has excellent mass productivity and is capable of reducing the production cost. This method for producing a metal nanocoil comprises: a step wherein a metal thin film is formed on the surface of a core that is formed of a nanofiber of a polymer in a state where a tension is applied to the core, thereby producing a metal-coated nanofiber; a step wherein the tension applied to the metal-coated nanofiber is relaxed; and a step wherein the metal-coated nanofiber is heated to a temperature that is equal to or higher than the boiling point or the thermal decomposition temperature of the polymer and equal to or lower than the melting point of the metal thin film in a state where the tension is relaxed, so that the core is vaporized and the thin film is shrunk into a coil shape, thereby forming a hollow metal nanocoil.
