The invention provides a metal nano-material with a vine-shaped structure and a preparation method and application thereof, and belongs to the technical field of nano-materials. According to the preparation method, the magnetic metal nanowire is prepared through a water phase reduction method, then a precursor and a stock solution containing the metal nanowire react together, petal-shaped metal nanoparticles grow on the magnetic metal nanowire, and therefore the metal nanometer material of a vine-shaped structure is obtained. The petal-shaped metal nanoparticles have good conductivity (electric field shielding effect) and can provide more pore structures at the same time, and absorption and loss of multiple reflections are improved; the metal nanowire has a one-dimensional structure, so that a conductive network (an electric field shielding effect) is easier to construct, and meanwhile, the metal nanowire has magnetism (a magnetic field loss effect). Therefore, the metal nano material with the vine-shaped str
