对PAN/PEO凝胶(5% PAN，5% PEO)在1.0 MeV电子束下进行了不同剂量的辐照。红外光谱测量表明，PAN/PEO凝胶辐照后发生了化学交联。分析结果指出，PAN/PEO的凝胶分数随着辐照剂量的增加而不断增加；其凝胶分数增长率的变化可以分为3个阶段，即快速增加阶段(0～39 kGy)、下降阶段(39～130 kGy)和稳定阶段(>130 kGy)。拟合发现，引入材料刚性参数β的半经验修正方程与未考虑材料刚性的Charlesby-Pinner方程相比，更符合实际测量值(对于该配比PAN/PEO，β为0.166)。交联度-辐照剂量曲线显示，交联度随辐照剂量的增加而增加，为设计新型能功能材料中所需的固定交联度的PAN/PEO凝胶提供了辐照剂量参考值。
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 out by 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 (0～39 kGy), decreasing stage (39～130 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 parameterβ in the half-experience equation (for PAN/PEO,β 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.
