Abstract

Polyacrylonitrile/polyethylene oxide (PAN/PEO, 5% PAN and 5% PEO) was irradiated by 1.0 MeV electron beam with different doses in this work. FTIR result indicated that PAN/PEO crosslinked after irradiation. It was pointed outby analysis that gel fraction of PAN/PEO increased with EB irradiation dose.The increasing rate of gel fraction could be divided into three stages, which were rapidly increasing stage (0 s 39 kGy), decreasing stage (39 s 130 kGy) and stable stage (more than 130 kGy). Theoretical calculation results showed that the values fitting by half-experience equation presented by Zhang Wanxi were closer to the measured values than Charlesby-Pinner equation fitting ones because of the introduction of rigidity parameter in the half-experience equation (for PAN/PEO, was 0.166). The curve of crosslinking degree vs irradiation dose showed that the crosslinking degree increased with the irradiation dose, and it could provide a referential irradiation dose when materials with fixed crosslinking degree were needed in new functional materials.
