| 摘要: | 将2种链段长度不同的聚苯乙烯-b-聚2-乙烯基吡啶(PS-b-P2VP)在氯仿或四氢呋喃中溶解后, 以一定比例混合, 在乙醇或甲苯蒸汽中退火自组装, 得到了一系列薄膜形貌和尺寸不同的自组装结构. 采用原子力显微镜研究了混合比例、溶剂和退火蒸汽对薄膜自组装结构的影响. 结果表明: 改变混合比例可以对薄膜自组装结构和尺寸进行有效的调控; 四氢呋喃相比氯仿更有利于混合体系薄膜自组装的相分离; 乙醇蒸汽可以有效地诱导混合体系的薄膜自组装. |
| Abstract: | In the experiment reported in this paper, the block copolymers polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) with different chain length were dissolved in chloroform or tetrahydrofuran, then mixed at definite ratio. The thin film annealing self-assembly in ethanol or toluene atmosphere is studied, and a series of self-assembly structures with different morphologies and sizes are obtained. The influences of blending ratio, solvent and annealing solvent on the thin film self-assembly are investigated using the Atomic Force Microscope (AFM). The results show that the thin film self-assembly structure can be effectively controlled by varying the blending ratio. Tetrahydrofuran is more beneficial solvent to the phase separation of thin film self-assembly of blending system than chloroform. It is found that ethanol can efficiently induce the thin film self-assembly of blending system. |
