- Abstract
- We report the effect of N(2), Ar, and O(2) plasma treatments on the surface properties of metals. The carbon atoms reduced more in O(2) and Ar plasma than in N(2) plasma due to a chemical reaction with O(2) plasma and large plasma density in Ar plasma. A water contact angle decreased after the plasma treatment regardless of the kinds of plasma gas, showing the increase in the hydrophilicity in surfaces. Synchrotron radiation photoemission spectroscopy data showed that the work function increased after N(2), Ar, and O(2) plasma treatments in sequence. This is due to the reduction of carbon atoms and the formation of O-rich surface in O(2) plasma case. (c) 2008 American Institute of Physics.
