Polytetrafluoroethylene(PTEE) was modified using plasma and ion beam treatments. Different morphologies were developed for each surface treatment method. contact angle, atomic chemical composition, and peel strength were measured after treating with various surface treatment methods. Plasma and ion beam treatment showed different adhesion strength. The different adhesion strengths were explained by morphology and atomic chemical composition of the treated surfaces. The argon plasma treated sample introduced vary unusual amount of oxygen on the surface and the surface was of relatively smooth layer with crater-like morphology. Ion beam treatment showed the form of spires whose dimensions were of several micrometers, depending on the ion dose, whereas the oxygen plasma treated samples showed short spires with globules on the top. It was speculated that the weak boundary layer of plasma treated samples are related to the weaker adhesion strength than that of ion beam treated PTEE.
