Jids 3. SUMMARY
on
iss. It We have shown that the differently structured rough surfaces show different adhesive
properties and can be tested by using a method based on force-distance
measurement of an adhering adhesive tape. The structured surfaces can be easily
oe manufactured by sandblasting or flame spraying as well as subsequent
electrochemical methods in order to achieve a hierarchial topography.
Moreover, the first experiments show that also rough metallic surfaces can be coated
and with tetraetherlipids, and so they represent a two-fold biomimetic transfer based on
W the lotos leaf surface topography and chemistry as well as durability of the
or biomolecular coating. Furthermore, long-term tests of the forementioned surfaces are
nic being developed. In this case the samples have to be tested during such a long
period of time as months and years. Systematic test of durability as well as
antiadhesive testing as a function of surface structure and chemistry will reveal if and
10W how some surface features may be of universal character and lead to a set of
experience-based standard surfaces. This would enhance and increase the number
of applications of antiadhesive surfaces in industry.
