中文摘要 | the evolution of morphologies of isothermally crystallized thin films with different thicknesses of poly(l-lactide-bethylene oxide) diblock copolymer was observed by optical microscopy (om) and atomic force microscopy (afm). dendritic superstructures stacked with lamellae were investigated in thin films with similar to 200 nm to similar to 400 nm thickness. the lamellar structure was a lozenge- or truncated-lozenge-shaped single crystal of plla confirmed by afm observations. the contour of the dendritic superstructures is hexagonal, and two types of sectors, [110] and [100], can be classified in terms of the chain-folding and crystal growth directions. these phenomena are due to the interplay of the crystallization of the plla block, the microphase separation of the block copolymer, and the effect of the film thickness. |
