An e.s.c.a. investigation of the surface oxidation of bisphenol A polycarbonate films induced by reactive oxygen species

The changes in surface chemistry of bisphenol A polycarbonate films on exposure to various reactive oxygen species have been examined using e.s.c.a. Oxygen uptake, as a result of ozonation involves reactions of both the gem dimethyl and phenyl moieties. Singlet oxygen does not react with polycarbona...

Description
Summary:The changes in surface chemistry of bisphenol A polycarbonate films on exposure to various reactive oxygen species have been examined using e.s.c.a. Oxygen uptake, as a result of ozonation involves reactions of both the gem dimethyl and phenyl moieties. Singlet oxygen does not react with polycarbonate. The results presented here indicate that the interpretation of oxidation mechanisms due to singlet oxygen sould be treated with caution when generating this species by the microwave discharge technique.
