Copolymer-assisted generation of three-dimensional patterns by replicating two-dimensional substrate motifs.
We use a three-dimensional self-consistent field model to study copolymer adsorption from polymer melts onto chemically heterogeneous substrates. We show that in situations where the copolymer sequence distribution is commensurate with the spatial distribution of the substrate chemical impurities, the two-dimensional substrate pattern gets transcribed into three dimensions and propagates into the polymer mixture. This transference scheme can assist in designing nanostructures that find use in various areas of science and technology.
