Durable hydrophobic structured surface

摘要

The present invention relates to a scratch-resistant micro- and/or nanostructured surface comprising a plurality of micro-scale and/or nano-scale surface elements, said surface being essentially unchanged when being subjected to 10 rubbing cycles according to A.A.T.C.C. test method 8-1972 using a cotton cloth and a total stamp weight of 300 g, and comprising a polymeric material having
- an elongation at break of at least 10%,
- an irreversible relative plastic deformation (permanent set) of less than 2% and a
- a tensile strength of at least 5 MPa. The present incvention furthermore relates to a hydrophobic micro- and/or nanostructured surface comprising a plurality of micro-scale and/or nano-scale surface elements and having a static contact angle against water of at least 90°, said surface comprising a polymeric material having
- an elongation at break of at least 10%,
- an irreversible relative plastic deformation (permanent set) of less than 2% and a
- a tensile strength of at least 5 MPa.
