The majority of common engineering polymers have inherently low surface energy and therefore exhibit poor adhesion characteristics. Plasma treatment offers a reliable and environmentally friendly method of both cleaning and activating the polymer surface, increasing the surface energy and wettability, resulting in greatly improved adhesion characteristics.
