| 摘 要： | 利用电子束高温辐照PTFE，制备出交联PTFE样。通过红外光谱法（IR）、差示扫描量热分析法（DSC）等各种方法研究辐射交联PTFE的性能。结果表明：与未辐照PTFE相比，交联PTFE的透明度明显增加，熔点下降，耐磨性能明显提高。

| Abstract: | Radiation - crosslinking of polytetrafluoroethylene was carried out at high temperature and the products were analyzed by various methods. It was shown that the crosslinked PTFE had a good transparency and lower melting point. In addition, abrasion resistance and the tensile strength of PTFE are also greatly improved by radiation crosslinking. |
