| 摘 要： | 采用蒙特卡洛方法研究了伴有化学反应A＋B C的三元混合物相分离体系畴的形貌和生长动力学行为。研究给出不同的淬火温度下反应扩散体系形成了的斑图的形貌,并给出在相分离后期嵌段共聚物浓度随着时间演化的标度规律：nC=t-γ。最后讨论化学反应速率对体系中共聚物浓度的影响,中度淬火温度下,在相分离后期,反应速率越小体系中共聚物的浓度相对越高。

| Abstract: | The Monte Carlo simulation is presented to explorer the effort of chemical reaction on the phase separation of ternary mixtures. The results demonstrate that in the intermediate quench temper- ature, the system forms a big double continuous phase, and the density of copolymer satisfies the scaling relations： nc = t .Finally, the influence of chemical reaction speed on density of copolymer is discussed.The result demonstrates that the bigger the chemical reaction rate,the less of diblock-copo- lymer produced in the system. |
