This review introduces some research progress of metallic function nanomaterials for inertial confinement fusion （ICF） targets. The flow-levitation method has been widely applied to produce single-element metallic and bimetallic nanopartieles, and to in-situ organically encapsulate them in combination with the dielectric-barrier discharge. These nanoparticles are compacted to form nanostructured materials with different densities in a vacuum-thermo oven. The nanostructured metals exhibit some more excellent mechanical and thermal properties than the bulk materials. Porous and specificshape nanometals have been synthesized or grown by the electrochemical methods, as shown in this review. Some of these nanomaterials have been applied to ICF physical experiments for obtaining better experimental results.
