摘要：

An X-ray photoelectron study of sulfonated polyethylene films, with different sulfonation degrees (SD) before and after pyrrole polymerization at their surfaces is presented. For SD values of about 2 g/m2 the outer surface of polyethylene film becomes fully sulfonated. Sulfonic groups which act as a counterion of the grown polypyrrole (PPy) monitor partially the fixation of PPy at the outer surface. A variation of the pyrrole rings/counterion ratio (7.4-3.9) depending on SD values has been found.
