Název v původním jazyce

The Effect of Processing of Polycaprolactone Films on Degradation Process Initiated by Aspergillus Oryzae Lipase

Popis výsledku v původním jazyce

Polycaprolactone (PCL) films with Mn = 18 kDa obtained by compression molding (CM) or solution casting (SC) were subjected to Aspergillus oryzae (AO) lipase action in a phosphate buffer at pH 7 at 37 degree Celsius. The appearance of randomly oriented cracks on the surface of incubated PCL films accompanied by a decrease of the weight-average molecular weight (Mw) by 10% was observed after 42 days. The increase of crystallinity and surface morphology pattern of PCL samples exposed to AO lipase action supported th fact that the degradation proceeded in the amorphous phase of the aged films. SC films were degraded faster, probably due to better accessibility of ester bonds in the amorphous phase of spherulites.
