| 摘要 |
The invention concerns a method for preparing a substrate one surface of which consists of a polymer, said polymer surface being oriented and nanostructured, said method including the following successive steps: a) brushing the polymer surface in an amorphous state of the substrate; b) contacting with a vapour of a solvent, the oriented polymer surface obtained at the end of step a), said solvent being selected such that: |deltapoly-deltasol|/[(deltapoly+deltasol)/2]<0.3, deltapoly and deltasol representing respectively the solubility parameters of the polymer and of the solvent, and gammasol<gammapoly, gammasol et gammapoly representing respectively the free surface energies of the solvent and the polymer. The invention concerns a substrate one polymer surface of which at least is oriented and nanostructured, and the various uses of said substrate.
