| 中文摘要 | we have followed the morphological evolution and crystallization process of spherical micelles formed by the mixture of polystyrene-b-poly(acrylic acid) (ps-b-paa) and polystyrene-b-poly(2-vinylpyridine)b-poly(ethylene oxide) (ps-b-p2vp-b-peo) (the core of the spherical micelles was made of p2vp and paa blocks through hydrogen bonding in neutral solvent n,n-dimethylformamide, dmf) via dmf vapor treatment. different phenomena, such as rupture of the film, formation of cylinder aggregates and regular square lamellae, were observed when the micelle film was treated in dmf for different times. at the early stage of annealing in dmf vapor, the micelle film became unstable and ruptured. cylinder aggregates, within which the peo blocks achieved the association and primary chain folding, formed as the mesophases before the nucleation of the peo single crystals at this stage. further treatment in dmf vapor resulted in the nucleation of the peo blocks at the corners of quasi-square lamellae. then a quite regular "sandwich" lamellar structure, constructed by a peo single-crystal layer covered by two tethered layers of other amorphous blocks on the top and bottom crystal basal surfaces, formed when the film of micelles was annealed in dmf vapor for sufficient times. |
