Abstract: Disclosed is an aluminum-polymer resin composite. The composite includes i) aluminum and ii) a polymer resin bonded to the aluminum after modification of the aluminum surface with at least one surface modifier selected from the group consisting of sulfur-containing diazole derivatives, sulfur-containing diamine derivatives, sulfur-containing thiol derivatives, sulfur-containing pyrimidine derivatives, and sulfur-containing silane coupling agents. The intensity ratios of C/Al, N/Al, O/Al, Na/Al, Si/Al, and S/Al in the composite are in the range of 9.75×10−6 to 9.5×10−1 at depths of 100 nm to 500 nm, as analyzed by secondary ion mass spectrometry (SIMS). The composite has improved adhesive strength between the metal and the resin while maintaining its tensile strength and air tightness even after thermal shock testing. The composite is produced through various processing steps, including pretreatment, appropriate surface roughening, thermal treatment and surface coating, to enhance the bonding strength between the metal and the resin. The use of compounds containing S, N and Si further increases the bonding strength between the metal and the resin.
