我们提出了一个简单的逆向设计策略，通过使用嵌段共聚物或二元均聚物共混物通过耗散粒子动力学模拟生成三维（3D）纳米粒子。我们发现，嵌段共聚物的自组装可以通过模板的定向作用来扩展其组成窗口，从而形成特定的三维形貌。我们还发现，一个二元均聚物共混物可以作为一个更好的候选人在反模板设计，因为他们有类似的性能恢复目标模式，成本低得多。这种策略被证明是有效的制造所需的拓扑结构的模板，和反向设计的想法揭示了更好的控制和设计的材料与复杂的纳米粒子。
We propose a facile inverse design strategy to generate three-dimensional (3D) nanopatterns by using either block copolymers or a binary homopolymer blend via dissipative particle dynamics simulations. We find that the composition window of block copolymers to form a specific 3D morphology can be expanded when the self-assembly of block copolymers is directed by templates. We also find that a binary homopolymer blend can serve as a better candidate in the inverse templating design, since they have similar performances on recovering the target pattern, with much lower cost. This strategy is proved efficient for fabricating templates with desired topographical configuration, and the inverse design idea sheds lights on better control and design of materials with complex nanopatterns.
