Self-assembly of block copolymers (BCPs) have gained a lot of interest, since these polymers are of great economical and industrial importance as attested by potential for use as scaffolds, membranes and templates for the fabrication of well-ordered structures with sizes in the nanometer range. Thin films made of BCPs have a morphology of hexagonally packed cylinders perpendicular to film surface. Therefore removal of the minor component of BCPs that forms the cylinders leads to a film with a narrow pore size distribution. By controlling the composition and architecture of individual components, tunable pore size can be obtained. In this work, the pore size and useful morphology of hexagonally packed cylinders are controlled by using blends of either polystyrene-block-poly(ethylene oxide)/polystyrene-block-polymethylmethacrylate or polystyrene-block-poly(ethylene oxide)/polymethylmethacrylate. Furthermore, functional group can be applied to pore surface of nanoporous films. |
