In a selective solvent for one of the blocks, diblock copolymers self-associate into micelles. These micelles can be coated onto substrates to form an ordered array of copolymer micelles, which can be served as a template to synthesize nanoparticles. In this study, we demonstrated feasible creation of an ordered array of a mixture of copolymer micelles having bimodal size distribution. For binary mixtures of small and large micelles, independently-prepared solutions of micelles were transferred onto substrates. By adjusting both size and number ratios of small to large micelles, a mosaic nanopattern, in which hexagonally ordered large micelles were enclosed by small micelles, was effectively fabricated. We utilized the mosaic nanopattern of binary micelles as a structured template for nanoparticle synthesis. For example, it was possible to fabricate arrays of two types of nanoparticles, in which large nanoparticles of one type were enclosed by small nanoparticles of the other type. |
