摘要

本文首次用X-光电子能谱（XPS）研究了F-40的辐射交联机理以及交联度的表征。用XPS方法获得的F-40凝胶化剂量为4.1 Mrad。并发现在特定的剂量范围内，F-40的交联程度最大。

Abstract

In this paper, radiation-induced crosslinking mechanism of F-40(copolymer of tetrafluoroethylene and ethylene) and characterization of the crosslinking density by X-ray photoelectron spectroscopy (XPS) have been first studied. The dose of gelation of F-40 calculated with a plot of F/C(ratio of fluorine to carbon) obtained from XPS against R(radiation dose) is 4.1 Mrad. It is found that the crosslinking density is the largest at a range of certain dose and it becomes smaller at other doses. The radiation dose to reach the maximum crosslinking density is approximately 12.1 Mrad.
