Description

technical field [0001] The invention relates to a nanostructure and a preparation method, in particular to a copper@magnetic metal@polymer coaxial three-layer nano-cable and a preparation method thereof. Background technique [0002] Since carbon nanotubes were discovered in 1991, they have been favored by researchers due to their excellent properties. The research has also expanded from the initial carbon nanotubes to polymer nanotubes, metal oxide nanotubes and metal nanotubes. With the continuous deepening of research, the application range of composite nanomaterials is wider, and the performance of materials can be better reflected. Due to their unique magnetic properties, magnetic nanomaterials have broad application prospects in the fields of magnetic storage, perpendicular magnetic recorders, medical sensors, and nanoelectronic devices, and thus become a hot spot in the material science community. At present, ferromagnetic metals are mainly used as research objects,...
