The experimental results show that the physical aging is an important means for improving the orientational stability of poled film because it can effectively decrease polymer's free volume and restrict the oriented polar molecules to rotate out of alignment.
将聚合物的物理老化引入到极化过程中 ,并研究了不同温度下的老化对极化聚合物取向稳定性的影响 。
Texture evolution and orientational stability of high-strength and low-expansion Fe-Ni alloy was investigated using pole figure and orientation distribution function.
