摘要
采用程序控温动态分析方法.以四氢呋喃为探针分子,通过考察四氢呋喃分子在PEEK样品上的程序升温解吸(TPD)行为,讨论了不同PEEK样品的结构特征.结果发现:探针分子与PEEK的相互作用受PEEK结构特征的影响;由探针分于四氢呋喃与PEEK的作用强度及与PEEK作用的探针分子量,可判断不同PEEK样品分子结构和结晶结构的差异.
The structural characteristics of various samples PEEK are studied by temperature programmed desorption with tetrahydrofuran as probe molecules. The results show that the interaction between PEEK and probe molecules is influenced by the structure of PEEK, the differences in the molecular structure and the crystalline structure amohg various PEEK samples can be distinguished by the interacting intensities of the PEEK and tetra hydrofuran and the quantities of the probe molecules.
