Abstract
|
We report a route to fabricate two-level structured self-adaptive surfaces (SAS) of polymermaterials. The first level of structure is built by a rough polymer film that consists of needlelike structuresof micrometer size. The second level of structure is formed by the nanoscopic self-assembled domains ofa demixed polymer brush irreversibly grafted onto the needles. By exposing the surface to solvents thatare selective to one of the components of the brush, we reversibly tune the surface properties. The large-scale surface structure amplifies the response and enables us to control wettability, adhesion, and chemicalcomposition of the surface over a wide range.
