We propose a facile inverse design strategy to generate three-dimensional (3D) nanopatterns by using either block-copolymers or binary homopolymer blend via dissipative particle dynamics simulations. We find that the composition window of block copolymers to form specific 3D morphology can be expanded when the self-assembly of block copolymers is directed by templates. We also find that binary homopolymer blend can serve as better candidate in the inverse templating design, since they have similar performance on recovering the target pattern, meanwhile with much lower cost. This strategy is proved efficient on fabricating templates with desired topographical configuration, and the inverse design idea sheds lights on better control and design of materials with complex nanopatterns.
