Abstract:

Biodegradable porous aliphatic poly(butylene succinate-co-ethylene succinate)s(PBES) was prepared through a direct polycondensation method in supercritical carbon dioxide(scCO2). The effects of reaction pressure, temperatures and duration time of scCO2 on the foaming behaviors of PBES were investigated. The obtained porous PBES were characterized by scanning electron micrograph(SEM), X-ray diffraction(XRD). The results showed that the porosity can reach over 55% and the diameter of the pores was in the range 50~200 μm. The crystallinity of PBES was decreased after scCO2 treatment.

Key words: PBES, biodegradable, Supercritical carbon dioxide, porous materials
