Abstract
Provided is a method of manufacturing the present disclosure a composite composed of copper and a polymer resin. According to an embodiment of the present disclosure, the method includes an electroless oxidation step of performing the electroless oxidization for the copper in a solution for electroless oxidation to form a porous oxide film having a roughened structure on the surface of the copper; and a step of bonding the copper with the polymer resin.
Claims10
A method of manufacturing a copper-polymer resin composite, the method comprising:
- a degreasing step of degreasing a surface of copper;
- an electroless oxidation step of performing electroless oxidization for the copper in a solution for electroless oxidation to form a porous oxide film having a roughened structure on the surface of the copper;
- and
- a step of bonding the copper with a polymer resin,
- wherein the solution for electroless oxidation is a mixed solution prepared by dissolving two or more substances selected from sodium sulfate, sodium hydroxide, sodium chlorate, sodium chlorite and sodium phosphate in water.
A copper-polymer resin composite, comprising:
- copper;
- and a polymer resin bonded to at least a region of the copper,
- wherein a porous oxide film having a roughened structure is formed on a surface of the copper bonded to the polymer resin, and
- the oxide film has a thickness of 50 to 800 nm.
