| 英文摘要 | A simple process of solvent annealing has been shown to produce ordered self-assembly structures of poly(styrene)-block-poly(4-vinylpyridine) (ps-b-p4vp)/poly(4,4 '-oxydiphenylenepyromellitamic acid) (poaa) block copolymer/homopolymer blends in thin film, where poaa chains selectively interact with p4vp blocks by strong interpolymer hydrogen-bonding. by simply exposing the thin film to benzene/nmp (0.97/0.03, in volume) vapor mixture, ordered microphase-separated structures with ps spherical microdomains distributed within p4vp/poaa complexes matrix were obtained. the formation of the microphase-separated structures could be attributed to the substantial mobility of ps blocks and p4vp/poaa complexes and enhanced repulsion between them under the benzene/nmp mixture vapor. when the volume ratio of benzene to nmp increased to 0.98/0.02, the increasing benzene in the mixture vapor induced the adhesive collision of spherical microphase-separated structures to form long "pearl necklaces". with increasing volume ratio of benzene to nmp to 0.99/0.01, an ordered "pearl necklace" array oriented parallel to the film surface formed. the self-assembly structures were studied by ftir spectroscopy, atomic force microscopy (afm), and transmission electron microscopy (tem). finally, possible mechanism of self-assembly and formation of microphase morphology was proposed.
