ABSTRACT

Nitrogen-containing plasmas are widely used to improve wettability, printability, bondability and biocompatibility of polymer surfaces [ 1, 2]. Several applications have been investigated and they all show that wettability and adhesion properties of various polymer surfaces improve after ammonia or allylamine plasma treatment. Holmes and Schwartz, for instance, treated ultra-high-strength polyethylene fibers using ammonia plasma [3] and found that fabrics treated with ammonia plasma became completely epoxy resin wettable and the interfacial adhesion strength increased by 40%.
