摘要
对聚甲醛(POM)进行了光加速老化试验和湿热老化试验研究,利用电子显微镜、差示扫描量热仪和X光电子能谱对材料在老化过程中的物理和化学性能进行了分析,结果表明,POM在老化过程中物理力学性能下降的主要原因是表面无定形区域的光氧化。
The physical and chemical changes of POM during accelerated photo-ageing test and humidity and heat ageing testare studied by means of Scanning Electron Microscope (SEM) .Differential Scanning Calorimetry (DSC) and X-ray Photoelectron Spec-troscopy (XPS). The test results show that as a result of the photo-oxidation of non-crystalline region, the physical and mechanical properties of POM in photo-ageing test are decreased.
