Local Structure Surrounding Implanted As+ Ions in Polysulfone Films
Published online by Cambridge University Press: 15 February 2011
Abstract
Results from As K-edge XAFS studies on polysulfone films implanted with 50 KeV As+ in the dose range of 1015 to 1016 ions/cm2 indicate that As reacts chemically with O atoms to form As- (3) 0 based molecular structures having As-0 bond lengths equal to 1.81±0.02 Å. In comparison to samples implanted in the dose range 101S to 1016 ions/cm2, the molecular environment surrounding As in polysulfone implanted at 1017 ions/cm2 has additional structure beyond the nearest-neighbor O atoms.
