Copolymer-assisted generation of three-dimensional patterns by replicatingtwo-dimensional substrate motifs - art. no. 022601

We use a three-dimensional self-consistent field model to study copolymer a dsorption from polymer melts onto chemically heterogeneous substrates. We s how that in situations where the copolymer sequence distribution is commens urate with the spatial distribution of the substrate chemical impurities, t he two-dimensional substrate pattern gets transcribed into three dimensions and propagates into the polymer mixture. This transference scheme can assi st in designing nanostructures that find use in various areas of science an d technology.
