摘要
采用改进的热激电流设备得到不同实验条件下(不同极化场强、极化温度、极化时间)的TSC曲线,研究不同测试条件对测量结果的影响。结果表明:选择适当的测试条件对测量的精确度有重要的意义;纳米粒子的存在有助于抑制聚合物分子链的运动和空间电荷效应。
The TSC curves of various testing conditions,such as different polarization field strength,poling temperature and poling time,were obtained with improved TSC equipment,and then the effects of different testing conditions on the testing results were studied.The results indicate that proper testing conditions are important for testing accuracy.The existence of nano-particle contributes to inhibit the motion of molecular chain of polymer and space charge effect.
