中文摘要	morphologies and structures determined by crystallization of the blocks, microphase separation of the copolymers, and vitrification of plla block in poly(l-lactide-b-ethylene oxide) (plla-b-peo) copolymers were investigated using microscopic techniques and synchrotron small angle x-ray scattering. the plla-b-peo copolymer films were crystallized from two different annealing processes: melt crystallization (process a) or crystallized from glass state of plla block after quenching from melt state (process b). the relationship between the crystalline morphology and microstructure of the copolymers were explored using saxs. the morphology and phase structure are predominated by crystallization of plla block, and greatly influenced by microphase separation of the copolymers. in process b, lozenge-shape and truncated lozenge-shaped plla crystals of nanometer scale can be observed. the crystalline morphology is markedly affected by the microstructure formed during the annealing process. star-shaped morphologies stacked with plla single crystals were observed.
