Cleanliness and hygiene have significantly increased the standard of living of the modern man and have substantially improved expectancy of life. Unfortunately both can only be sustained with the huge and expensive effort of constant cleaning. Extremely helpful would be surfaces that clean themselves by the use of water. In the last two decades, plenty of such surfaces have been artificially produced. These always are chemically hydrophobic and rough, whereas the roughness often is of double scale. All previously constructed surfaces however have been quickly destroyed by abrasion.

In this thesis, strategies to stabilize double-scale raspberry architectures have been developed. Novel larger macro raspberry particles were designed. These have successfully been brought to a sustainably stable and ultrahydrophobic surface. Furthermore, a still unanswered question, of which structural principle is decisive for the cleaning effect, was herewith researched.
