THE COATING METHOD HAVING EXCELLENT DURABILITY FOR SALT SPRAY TEST

摘要

The present invention is a thin film that improves the corrosion resistance and film adhesion to the brine, as well as to block an electromagnetic wave efficiently relates to a coating method having the electromagnetic shielding structure. ; To this end, the present invention is, as the material for electromagnetic shielding and electromagnetic wave shielding one embodiment the coating layer composed mainly of copper on a plastic substrate is superior conductivity, coating a layer of indium oxide as a main component indium as a top layer over the corrosion resistance of the brine, that is, is characterized in that for improving the salt water. ; In addition, as a main component a high conductivity copper coating a layer separate to that for the coating layer composed mainly of indium, and the electromagnetic wave shielding on the plastic substrate before performing the conductive film is characterized in that for improving the adhesion of the coating layer as a main component an excellent electromagnetic shielding copper .
