摘要: 本文首次用XPS研究了聚偏氟乙烯的辐射交联机理,交联度的XPS表征。计算出聚偏氟乙烯的β值为0.7,发现聚偏氟乙烯的辐射交联的溶胶分数与辐照剂量的关系符合我们提出的通式[1]。用XPS方法求得聚偏氟乙烯的凝胶化剂量为1.59mrad。

Abstract: Radiation-induced crosslinking mechanism of poly (vinylidene fluoride) and characterization of the crosslinking density by XPS have been first studied. The calculated β value of poly (vinylidene fluoride). is 0.7. It is found that the radiation-induced crosslinking of poly (vinylidene fluoride) is in agreement with the general expression, in which the sol fraction is telated to radiation dose[1]. The dose of gelation of poly(vinylidene fluoride) obtained by XPS is 1.59 mrad.
