Abstract
Polytetrafluoroethylene (PTFE) was implanted in vacuum by argon ions. The i nfluence of experimental parameters was studied by varying ion energy from 2 to 20 keV with the same dose of 1.4 x 10(17) ions/cm(2), The ion energy s trongly affected the surface composition, microstructure, and wettability o f PTFE. All as-implanted PTFE samples were aged in air for 1 year. After ag ing, the surface-restructuring behavior was observed on the surface of samp les implanted with ion energy of 2 and 5 keV. The water contact angle of ag ed samples implanted with ion energy of 5 and 10 keV decreased up to 22 deg rees and 11 degrees, respectively. (C) 2001 Published by Elsevier Science B .V.
