Abstract
A metal composite, a method of preparing the metal composite, a metal-resin composite, and a method of preparing the metal-resin composite are provided. The metal composite comprises: a metal substrate comprising a first layer formed on a surface of the metal substrate and an anodic oxidation layer formed on the first layer. The first layer comprises a first pore having an average diameter of about 10 nanometers to about 1 millimeter, and the metal composite comprises aluminum alloy or aluminum. The anodic oxidation layer comprises a second layer contacted with the first layer of the metal substrate and a third layer formed on an outer surface of the second layer, and the second layer comprises a second pore having an average diameter of about 10 nanometers to about 800 microns, and the third layer comprises a third pore having an average diameter of about 10 nanometers to about 800 microns.
