    摘要： The present invention relates to a method for preparing a metallic membrane, more particularly to a method for preparing metallic membranes, which comprises dissolving a transition metal of Period 3 and its alloy particle powder and synthetic polymer in a fixed ratio; radiating or casting to prepare a membrane precursor; oxidizing the synthetic polymer on the membrane precursor under a mixed gaseous atmosphere of nitrogen and hydrogen; and sintering the membrane precursor at a predetermined temperature. The metallic membrane prepared by the process of the present invention has excellent mechanical and chemical properties and enables to maintain a relatively small pore size and high porocity than traditional membranes. Therefore, it is useful for water treatment.

    摘要： A separator includes a planar non-woven fabric substrate having a plurality of pores, and a porous coating layer provided on at least one surface of the non-woven fabric substrate and made of a mixture of a plurality of inorganic particles and a binder polymer, wherein the non-woven fabric substrate is made of superfine fibers having an average thickness of 0.5 to 10 μm, and wherein, among the pores in the non-woven fabric substrate, pores having a wide diameter of 0.1 to 70 μm are 50% or above of the entire pores. The above separator having the porous coating layer may generate the generation of leak current without increasing a loading weight of the porous coating layer since the non-woven fabric substrate having a controlled pore side by using superfine fibers of a predetermined thickness is used.
