Improving Long Range Order in Block Copolymer based Nanotemplates — •Marcus Böhme, Bhanu Nandan, and Manfred Stamm — Leibniz-Institut für Polymerforschung Dresden, Hohe Str. 6, 01069 Dresden

Thin films of block copolymers and block copolymer based supramolecular assemblies (SMA) are promising candidates for the generation of self assembled templates. One of the biggest challenges in such soft matter systems is the creation of nanostructures which are uniformly ordered on a large scale. In most cases the long range ordering in block copolymer based thin films is either not sufficient for possible applications e.g. in storage technology or can only be achieved with expensive and time-consuming pre-patterning methods (guided self assembly).

It has been shown, that an appropriate treatment with solvent vapours can improve the ordering in thin films of block copolymers[1] or SMA[2] at least on a scale of a few micrometers. We would like to present our recent results on the improvement of the solvent annealing process and the resulting effects on the long range order in thin films of Poly(styrene-b-4-vinyl pyridine) (PS-P4VP) as an example for block copolymer templates and thin films of PS-P4VP with 2-(4-Hydroxyphenylazo)benzoic acid (HABA) as an example of SMA templates.
