一、前言热刺激电流技术能灵敏地反映聚合物的分子运动,以及电荷在聚合物中的贮存、转移过程,是一门较好的热分析技术在国内也已得到愈来愈广泛的应用。聚合物试样的极化方式不同,其热刺激电流谱也不同。本文讨论采用常规试验方法所得到的热刺激电流谱。常规方法试验程序是:试样升温至一定的极化温度,施加直流电场并使试样充分极化,然后使试样在存在电场的情况下冷却至低温,再除去电场,使试样线性升温,测得其热刺激去极化电流与温度的关系──热刺激电流谱。试验是在自 I. INTRODUCTION Thermal stimulation current technology can sensitively reflect the molecular movement of polymers and the storage and transfer of charges in polymers. It is a good thermal analysis technique that has been applied more and more widely in China. Polarization of polymer samples in different ways, the thermal stimulation current spectrum is also different. This article discusses the thermal stimulation current spectra obtained using routine experimentation. The conventional method test procedure is: the sample is heated to a certain polarization temperature, the DC field is applied and the sample is fully polarized, and then the sample is cooled to a low temperature in the presence of an electric field, then the electric field is removed to make the sample linearly heated , Measured the thermal stimulus depolarization current and temperature relationship ─ ─ thermal stimulation current spectrum. Test is in self
