Block copolymer(BCP) self-assembly has emerged as a powerful tool for nanopatterning and nanofabrication. However, BCP self-assembly creates only simple, periodic patterns that are predetermined by the composition, molecular weight. Several strategies to direct the self-assembly of BCPs have been proposed for effective control of BCP nanostructures. Combining two self-assembling materials on different characteristic length scales can provide efficient route to generate complex surface patterns. In this work, we offer a simple route to create nanopatterns by colloidal particles lithography and BCP self-assembly. First, colloidal particles are deposited on the substrate to form colloidal crystals, and then BCPs are coated on colloidal crystals so that they are able to guide BCP self-assembly. Combination of two self-assembling materials with variation in characteristic size and surface properties of templates has been shown to lead to the morphology of BCPs. |
