| 中文摘要 | in this letter, crystal growth of a symmetric crystalline-amorphous diblock copolymer, poly(styrene-b-epsilon-caprolactone) (ps-b-pcl), in thin films was investigated by atomic force microscopy (afm), relief structures of holes and islands were formed during annealing the film at the molten state, and the in situ observation of subsequent crystal growth at room temperature indicated that the crystals were preferred to occur at the edge of holes or islands and grew into the interior area. it was concluded that the stretched pcl blocks at the edge of relief structures, caused by material transportation or deformation of the interface, could act as nucleation agents during polymer crystallization. the crystal growth rate of individual lamellae varied both from lamellae to lamellae and in time, but the area occupied by crystals increased constantly with time. at 22 degreesc, the growth rate was 1.2 x 10(-2) mum(2)/min with the scan size 2 x 2 mum(2). |
