Research Abstract |
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.
