crystallization of PCL. Segregation of amorphous component during primary crystallization was evidently observed from TEM images which showed stacks of few lamellae located between crystals consisting dense lamellae stacks. By changing the crystallization conditions, shape recovery was associated with the melting of crystals formed during secondary crystallization of PCL in the range of body temperature, fulfilling
the essential requirement of medical applications.
