摘要

The (bio)degradation of aliphatic polyesters, poly(ε-caprolactone) (PCL), poly[(R)-3-hydroxybutyrate] (R-PHB), and poly(L- lactide) (PLLA) films in natural natural dynamic seawater was investigated using polarizing optical microscopy, gravimetry, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), and tensile testing. The results were compared with those repo- ted for the polyester films biodegraded in the controlled static seawater to reveal the physical effects in the natural dynamic seawater on the degradation of the aliphatic polyesters.
