Title:
METHOD FOR PRODUCING COMPOSITE BY LASER IRRADIATION, AND COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2022/172972
Kind Code:
A1
Abstract:
Provided is a composite production method that stably produces a composite in which a boundary distinctly divides a coating layer from a core containing a metal, ceramic, or combination thereof, and in which there are no gaps between the core and the coating layer. The composite production method comprises: preparing a linear material that contains a metal, ceramic, or combination thereof; immersing the linear material in a first dispersion in which a first solid nanomaterial is dispersed; and, while irradiating a first laser light onto the linear material that has been immersed in the first dispersion, moving a condensed region of the first laser light along the linear material to form, in at least a portion of the surface of the linear material, a first coating layer constituted of the first solid nanomaterial, thereby forming a core/first coating layer composite wherein the core is constituted of the linear material. The first solid nanomaterial is constituted of at least one selected from the group consisting of metal oxides, nonmetal oxides, ceramics, metals, and resins.
