| 中文摘要 | crystallization and phase behavior in solution-cast thin films of crystalline syndiotactic 1,2-polybutadiene (s-1,2-pb) and isotactic polypropylene (i-pp) blends have been investigated by transmission electron microscopy (tem), atomic force microscopy (afm) and field-emission scanning electron microscopy (fesem) techniques. thin films of pure s-1,2-pb consist of parallel lamellae with the c-axis perpendicular to the film plane and the lateral scale in micrometer size, while those of i-pp are composed of cross-hatched and single-crystal-like lamellae. for the blends, tem and afm observations show that with addition of i-pp, the s-1,2-pb long lamellae become bended and i-pp itself tends to form dispersed convex regions oil a continuous s-1,2-pb phase even when i-pp is the predominant component, which indicates a strong phase separation between the two polymers during film formation. fesem micrographs of both lower and upper surfaces of the films reveal that the s-1,2-pb lamellae pass through i-ppconvex regions from the bottom, i.e. the dispersed i-pp regions lie on the continuous s-1,2-pb phase. the structural development is attributed to an interplay of crystallization and phase separation of the blends in the film forming process. |
