Research overview:
Observation of appearance of various test pieces after testing moisture-resistance and water-resistance, and measurements of tensile strength, stiffness, absorbed moisture, and blocking temperature are carried out to apply biodegradable polymers to practical products. Rheological characteristics of the biodegradable polymers, which is a key factor deciding casting properties, are measured according to capillary rheometer method and bar flow test method, to contribute to study of their evaluation technique.
