Figure 5.

Platinum nanowires templated from laser-aligned cylinder-forming PS-b-P2VP homologues of different molecular weight obtained by the optimized SS-LZA procedure (24 W, 90 °C base temperature, 8 cycles at 0.32 mm s^–1). (a) Orientational order parameters η that were calculated from FFTs of SEM images indicate high quality of BCP morphology alignment. (b) AFM height images and their cross sections reveal the topography of the wires replicating the cylindrical shape of the poly(2-vinylpyridine) cylindrical domains.
