Abstract
The present disclosure relates to a method for preparing a metal-polymer resin composite with excellent bonding strength and bonding uniformity. The method includes a pretreatment step (S1) of etching a metal member, an electrolysis process step (S2) of forming an adhesive coating layer on a surface of the pretreated metal member, a drying step (S3) of drying the metal member with the adhesive coating layer formed on the surface, and an injection-molding process step (S4) of bonding a polymer resin to the dried metal member, and the electrolysis process is performed in an electrolyte solution containing a sulfur-containing compound and a metal chelate compound.
