摘要In order to predict (center dot) OH and (center dot) H radicals initiated degradation of proton exchange membrane (PEM) based on polymers obtained by radiation-induced grafting of styrene or alpha-methylstyrene on different polyolefin, isopropyl benzene sulfonic acid (IPBS) and tert-butyl benzene sulfonic acid (TBBS) were taken as model compounds for PEM with and without alpha-H, respectively. Results indicated that (center dot) OH radicals played a vital role in PEM degradation. Eighty-nine percent of (center dot) OH radicals reacted with IPBS to form benzylic radicals by electron transfer and subsequent deprotonation reactions. Benzylic radicals can react with O-2 to form peroxyl radicals, which leads to PEM degradation. TBBS, without alpha-H, reacted with (center dot) OH or (center dot) H radicals, benzylic radicals would not be generated, and only adducts were formed. Adducts have less influence on the stability of TBBS than benzylic radicals. In this work, we elucidated that PEM, without alpha-H, with similar structures to TBBS, had a stronger resistance to oxidative degradation than PEM with alpha-H, with similar structures to IPBS.
