“…2,7,10,47 In many PEO-b-PCL, PCL-b-PLLA and PEO-b-PLLA diblocks copolymers, morphological changes with temperature and composition have been observed: from well-defined Maltese cross spherulites and concentric spherulites to spherulites with continuous banding extinction patterns. 29,33,47,51,53 For instance, PEO-b-PLLA diblock copolymers with PLLA content between 71 and 32 % exhibit PLLA banded spherulites. 52 However, based on the observations of Huang et al 51 in the same diblock copolymers, the branching morphology developed as PLLA content in the terpolymers is lower (see Fig 8a, left) might be a result of the richer PCL-PEO amorphous phase that surrounds the proximity of the PLLA lamellae and disturbs further growth in their immediate vicinity.…”
