Method for treating surface of polymer or composite material using low-pressure plasma and Method for adhesion comprising the same

摘要

The present invention is a method of improving the adhesion performance of an adhesive containing a polymer or a composite material to an adhesive, wherein plasma treatment is performed with plasma derived from an inert gas on the polymer or composite material, and the plasma treatment is plasma under atmospheric pressure. It relates to a plasma surface treatment method of a polymer or composite material carried out under pressure. As a result, functional groups such as ether groups, ester groups, and amine groups are formed on the surface of a polymer or composite material having a low affinity with a curable adhesive such as epoxy, and the surface is activated, thereby increasing affinity and wettability with a curable adhesive such as epoxy to improve adhesion. can be greatly improved.
