The effects of electron beam (EB) irradiation of 0.22 MGy on the adhesive peeling load (Lp) of composites laminated with polypropylen (PP) and polydimethylsiloxane (PDMS) polymers films were investigated. EB irradiation enhanced the mean Lp from 7.0 mN for untreated composite to 23 mN for 0.22 MGy EB irradiated one without glue. Since EB irradiation generated dangling bonds with electrons in PP, they probably induced the polarization of terminated atoms of PDMS, as well as enhancement of effective interface area, and then atrracted for each polymer at the interface. Results indicated that EB irradiation at 0.22 MGy enhanced the Lp, therefore, it was concluded that EB irradiation was probably a useful tool for quick lamination of different polymers with sterilization.
