聚四氟乙烯(PTFE)在高能辐射下形成网状结构的报道尚未见报道。研究结果表明，在330-340℃真空条件下进行辐照时，聚四氟乙烯可以通过辐照而发生交联。发现交联型聚四氟乙烯在高温力学性能和辐射稳定性方面都有很大的改善。
Polytetrafluoroethylene (PTFE) has never been reported to form a network structure when subjected to high energy radiation. Results obtained in this work indicates that when irradiation is performed under 330-340-degrees-C in vacuo PTFE can be crosslinked through irradiation. Crosslinked PTFE was found to pin a great improvement in both high temperature mechanical properties and radiation stability.
