Schematic of the strain-alignment approach. (a) A spin-cast pBTTT film is transferred onto a PDMS slab, (b) the film is strained while heated into its liquid crystal phase, (c) the strained film is then transferred onto a secondary substrate, (d) the strained film is transferred onto another PDMS slab, (e) and the film is transferred onto a final OTS-treated substrate.
