Dominant factors influencing dielectric properties in several biodegradable polymers

对于典型的可生物降解的聚合物，即聚对苯二甲酸乙二醇酯琥珀酸酯、聚丁二酸丁二醇酯、聚己内酯、聚丁二酸己二酸丁二醇酯、聚己二酸对苯二甲酸丁二醇酯、淀粉酯和聚-L-乳酸，通过进行先进的测量来检查晶体结构对其介电性质的影响，所述测量例如使用同步辐射的光致发光、太赫兹时域光谱、和密度泛函理论的数值计算。因此，获得了许多知识的主导因素影响的介电性能的生物可降解聚合物。这将极大地促进环境友好型电介质材料的发展。

For typical biodegradable polymers, namely, polyethylene terephthalate succinate, polybutylene succinate, polycaprolactone, polybutylene succinate adipate, polybutylene adipate terephthalate, starch ester, and poly-L-lactic acid, effects of the crystal structure on their dielectric properties were examined by conducting advanced measurements such as photoluminescence using synchrotron radiation, terahertz time domain spectroscopy, and numerical calculations using density functional theory. As a result, much knowledge was obtained on the dominant factors influencing the dielectric properties of biodegradable polymers. This will greatly contribute to the development of eco-friendly dielectric materials.
