Block copolymer (BCP) self-assembly is a useful platform to generate well ordered periodic nanostructures of micelles, consisting of a soluble corona and an insoluble core in a selective solvent for one block. It is well known that solvent annealing of the BCP template leads to a fingerprint pattern with cylinders embedded within the matrix. The surface reconstruction using selective solvent for one block induces core-corona inversion and the core block swell on the surface. Herein, combining the above-described aspects, we suggest strategy to induce 2D arrays of strings of micelles via reconstruction of 2D arrays of BCP inverse micelles. Concretely, 2D nanowire arrays of PS-b-PVP inverse micelles were first made by annealing in selective solvent vapor for both blocks. 2D arrays were subsequently treated with a preferential solvent for the PVP. Utilizing this, metal NP arrays were obtained by dipping in metal precursor solution followed by removal of BCP and reduction of the precursor. |
