In the first part of this thesis, Stress relaxation method set up in the software of DMA was used to perform the aromatic and aliphalic (D2192-BAPP) PI film stretching process. To study the optical anisotropies property to the light leakage from the crossed polarizers, we put the stretched samples into one set of crossed polarizers and as expected, the stretched PI films could reduce the light leakage at view angle of ±45 deg, and exhibited a visually observed compensating property of an A-plate. No color shift wasobserved, and the birefringence was very uniform. These results prove a uniform birefringence can be obtained by a stretched process for PI films.
首先,我们以动态机械分析仪的应力缓和模式对芳香族FDA-BAPP PI及脂肪族D2192-BAPP PI薄膜进行拉伸实验,并将拉伸后的PI薄膜置於一组相互交差的偏光片中观察其光学异向性,发现拉伸后的PI薄膜试片可以降低在±45o视角的漏光的效果,展现出如同A-Plate的光学补偿特性,所显现的光学补偿效果相当的均匀而且没有色偏的情形发生,证实以拉伸方法可以造成PI薄膜很均匀的双折射效应。
