Abstract

The invention concerns structured surfaces with elevations and recesses, which contain polyhedral oligomeric silicon oxygen cluster units. Such surfaces can contain e.g. hydrophobic, abrasion and scratch-proof characteristics and/or self-cleaning characteristics. Likewise such surfaces can be overcoated with an antireflection film. The surfaces according to invention are formed by fixing polyhedral oligomeric silicon-oxygen cluster compds. a surface. These compds. are applied to the surfaces as additives in coatings and inks. A typical silsesquioxane cage was manufd. by stirring 446 g iso-BuSi(OMe)3 in 4300 mL MeCO with 6.4 g KOH in 200 mL water for 3 days. [on SciFinder (R)]
