这些电影的表面形态学 poly [styrene-b-(ethylene-co-butene )-b-styrene](SEBS)have 由使用龙头模式学习了原子力量显微镜学(TM-AFM ) 。嵌段共聚物的电影被纺纱涂层在不同答案表面上在云母和扔 bysolvent 上两个都准备。为纺纱涂层样品,答案集中,溶剂,和退火的温度的效果被调查。改变答案的集中没在 blockcopolymer.The 微观结构的电影的形态学上有差别,这被显示出在热退火期间是相当稳定的;仅仅领域的尺寸向平衡配置变化。然而,溶剂的退火能显著地改变不同选择性溶剂被用于的 themicrostructures.When 电影纺纱涂层,不同形态学能被获得并且由 solvents.Asexpected,在顶的重要不同形态学和底部的不同溶度参数解释铸型薄膜的表面被观察。最高的表面的图象揭示柱体微领域,当底部表面的那些是球形的形态学时。
Surface morphologies of the films of poly [styrene-b-(ethylene-co-butene)-b-styrene] (SEBS) have been studied by using tapping-mode atomic force microscopy (TM-AFM). The films of block copolymer were prepared both by spin-coating on mica and by solvent-casting on different solution surfaces. For spin-coating samples, the effect of solution concentration, solvent, and annealing temperature are investigated. It is shown that changing the concentration of the solution makes no difference on the morphology of the film of the block copolymer. The microstructures are quite stable during thermal annealing; only the size of the domains changes toward the equilibrium configuration. However, solvent annealing can notably change the microstructures. When different selective solvents are used for film spin-coating, different morphologies can be obtained and explained by the different solubility parameters of the solvents. As expected, significant different morphologies in the top and the bottom surfaces of the casting films were observed. The images of the top surfaces reveal cylinder microdomains, while those of the bottom surfaces were spherical morphologies.
