Abstract
In this work, the chemical transformations induced by 5 keV protons (10(6) ion cm(-2)) at the surface of 0.4 mu m polyacrylonitrile and polymethacrylo nitrile films are analysed by XPS and IRRAS. Spectroscopic changes in both the polymers are globally similar, the most significant feature being a low er relative concentration of nitrogen with respect to carbon closer to the surface. Quantitatively, this change is more marked in the case of polyacry lonitrile which suggests a direct relation with the hydrogen in cl to the n itrile function. (C) 1999 Elsevier Science B.V.
