Abstract

We report about the fabrication of polymeric nanotemplates for the fabrication of regular arrays of nanocylindrical domains. Using combi-like macromolecules obtained by complexation of polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) copolymer with a low molecular weight surfactant pentadecylphenol (PDP) we prepared thin polymer films deposited on a neutral substrate. The block-copolymer – PDP complex segregates into cylindrical morphology formed by P4VP-PDP fragments. The PDP molecules were easily removed by selective solvent (methanol) after annealing of the film. The resulting morphology consists of cylindrical channels of 7-8 nm in diameter oriented perpendicular to the substrate and regular packed in the hexagonal lattice with the period of 21 nm. Dry plasma etching, Atomic Force Microscopy (AFM), and Grazing Incidence Small Angle X-ray Scattering (GISAXS) were employed to characterize the films.
