Abstract

Abstract: The degradation behavior of poly(ε-caprolactone)(PCL)/poly(d,l-lactide)(PLA) blend films prepared by solution casting method have been studied in the phosphate buffer solution containing pseudomonas lipase(PS). PCL was found to be degraded and PLA remained as before. The SEM results indicated that the change both in the surface and inside of the film was owing to the degradation of PCL component in the blends.

Key words: polycaprolatone-polylactide blend, enzymatic degradation, morphology
