Abstract
The present application relates to an asymmetry composite material and a method for preparing the same, which provides a composite material comprising a metal porous body (metal foam or the like) and a polymer component, and provides a method for preparing a composite material, wherein the polymer component is formed in an asymmetrical structure on both sides of the metal porous body (metal foam or the like), and a composite material prepared in such a manner.
Claims3
A method for preparing an asymmetry composite material, the method comprising:
- providing a metal porous body that comprises one side and an other side opposite to the one side, wherein a resin layer is present on the one side, wherein the resin layer is a pressure-sensitive adhesive layer;
- applying a first polymer layer to the other side of the metal porous body, wherein the other side of the metal porous body means a surface of the metal porous body on which the resin layer is not present;
- curing or crosslinking the first polymer layer after applying the first polymer layer;
- removing the resin layer after the curing or crosslinking the first polymer layer;
- washing resin layer residues after removing the resin layer;
- and
- after removing the resin layer, applying a second polymer layer to the one side of the metal porous body from which the resin layer has been removed,
- wherein a component of the second polymer layer does not exist on the surface in which the first polymer layer exists, and a component of the first polymer layer does not exist on the one side in which the second polymer layer exists.
