摘要
本文采用差示扫描量热法,两段升温模式,以10℃/min加热速度,从30℃加热到150℃,测定了4个聚丙烯腈纤维样品的玻璃化转变温度,探讨了加热方法和样品量试验条件,得到了准确可靠的玻璃化转变温度。
The glass transition temperatures （Tg） of four polyacrylonitrile fibers were determined by means of differential scanning calorimetry（DSC） with two step heating program at 10℃/min heating rate.The heating range was from 30℃ to 150℃.We studied the test conditions of the heating method and the sample weight so that we got the accuracy and reliable glass transition temperature.
