Polysulfones are materials of great technological interest due to their applications as polymeric membranes, resists for microelectronics, heat-resistant materials in aerospace applications, matrices for composites, etc. It has been shown that ion beam treatment applied in the low-keV range is a suitable way to modify some relevant properties of polysulfones, such as solubility or electrical conductivity (117, 118], XPS is probably the most suitable analytical method for the characterization of ion-beam-induced changes in the composition and chemical state of polysulfone,s, e.g of aromatic polyfether sulfone) (PEiS) [119, 120).
