Claim 0:
1. A method for preparing a composite material that comprises a metal foam having a first surface and a second surface opposite the first surface, the method comprising:
irradiating with light only the first surface of the metal foam on which a photo-curable composition is present, thereby forming a polymer component on the first surface; and
removing uncured photo-curable composition from the second surface of the metal foam after irradiation,
wherein the metal foam is in a film shape, wherein the polymer component has an area ratio (A) on the first surface and the polymer component has an area ratio (B) on the second surface and a ratio (B/A) is in a range of 0 to 0.90,
wherein the area ratio (A) of the polymer component present on the first surface is 90% or more.
