12 Claims

1. A metal-plastic composite material, comprising:

a metal layer;

a plastic layer on at least one surface of the metal layer; and

a thin film layer provided between the metal layer and the plastic layer,

wherein the thin film layer includes (i) a silane coupling agent at an amount of 95 to 99 weight %, and (ii) a phenoxy-based resin at an amount of 1 to 5 weight % based on a total weight of the thin film layer,

wherein the silane coupling agent is at least one selected from a group consisting of 6-[[3-(triethoxysilyl)propyl]amino]-1,3,5-triazine-2,4-dithiol monosodium (TES) and tetramethoxy silane,

wherein the metal layer and the plastic layer are bonded to each other by a covalent bond with the silane coupling agent.
