Abstract
Disclosed is a method of attaching heterogeneous materials, for example, a metal plate and a polymer resin, by greatly improving the adhesive strength between the heterogeneous materials, for example, the metal plate and the polymer resin. Particularly, the method may include pretreating the surface of a metal plate with an aromatic compound containing a pyrogallol group to bind the pyrogallol group to the surface of the metal plate and coating the pyrogallol-group-bound metal plate with a polymer resin, thereby greatly improving the adhesive strength between the metal plate and the polymer resin through a simple process.
