光学活性结晶聚合物由于其不对称的晶体结构而具有剪切压电性。在这项研究中，探索一种新的剪切压电聚合物，我们已经集中在一个酰亚胺环结构和合成的光学活性聚琥珀酰亚胺（PSIs），最小结构的光学活性聚酰亚胺。结果，获得了光学活性PSI，并且我们观察到取向的光学活性PSI膜显示剪切压电性。此外，光学纯度和分子量都是压电性能的重要因素。这是第一次报告的剪切压电性的光学活性聚酰亚胺，我们在这里确定一个新的类别的剪切压电聚合物。(C)2015日本应用物理学会
Optically active crystalline polymers have shear piezoelectricity owing to their asymmetric crystal structure. In this study, to explore a novel shear piezoelectric polymer, we have focused on an imide ring structure and synthesized optically active polysuccinimides (PSIs), the minimum structure of optically active polyimides. As a result, optically active PSIs were obtained, and we observed that oriented optically active PSI films show shear piezoelectricity. Furthermore, both optical purity and molecular weight are significant factors in piezoelectric performance. This is the first report of the shear piezoelectricity of optically active polyimides, and we identify herein a novel category of a shear piezoelectric polymer.
