| 中文摘要 | in this paper, the authors have systematically studied the microphase separation and crystallization during spin coating of an abc triblock copolymer, polystyrene-b-poly(2-vinylpyridine)-b-poly(ethylene oxide) (ps-b-p2vp-b-peo). the microphase separation of ps-b-p2vp-b-peo and the crystallization of peo blocks can be modulated by the types of the solvent and the substrate, the spinning speed, and the copolymer concentration. ordered microphase-separated pattern, where peo and p2vp blocks adsorbed to the substrate and ps blocks protrusions formed hexagonal dots above the p2vp domains, can only be obtained when ps-b-p2vp-b-peo is dissolved in n,n-dimethylformamide and the films are spin coated onto the polar substrate, silicon wafers or mica. the mechanism of the formation of regular pattern by microphase separation is found to be mainly related to the inducement of the substrate (middle block p2vp wetting the polar substrate), the quick vanishment of the solvent during the early stage of the spin coating, and the slow evaporation of the remaining solvent during the subsequent stage. on the other hand, the probability of the crystallization of peo blocks during spin coating decreases with the reduced film thickness. when the film thickness reaches a certain value (3.0 nm), the extensive crystallization of peo is effectively prohibited and ordered microphase-separated pattern over large areas can be routinely prepared. |
