| 英文摘要 | Polyacrylonitrile fibers were pre-oxidized in air at temperatures from 180 degrees c to 265 degrees c. the morphological rearrangement, chemical reactions and the variation of thermal properties during the continuous thermal oxidative stabilization were characterized by x-ray diffraction, ft-ir, dsc and tg. results showed that; (1) when the pre-oxidative temperature was below 200 degrees c,the cyclization reaction was slow. when the temperature increased from 200 degrees c to 230 degrees c, the cyclization index increased rapidly and the reaction was drastic. the reaction rate reduced after the pre-oxidative temperature reached above 230 degrees c. (2) the pre-oxidation reactions were first initiated in an amorphous region, thereafter the reactions propagated to the crystalline regime at high temperatures where reactions were drastic. (3) when the pre-oxidative temperature was below 210 degrees c, the crystal size increased, corresponding to stress crystallization. the crystallite size decreased rapidly after the pre-oxidative temperature reached above 210 degrees c. |
