Claims20
A microstructured film comprising inorganic-organic hybrid polymers, wherein the structure thereof is composed by repetitive elements having each one of the following shapes:
- I) a shape which vertical cross-section is in the form of a 4-sided polygon in which an upper side and a lower side are parallel and have a different length;
- II) a shape which vertical cross-section is a concave plane;
- III) a shape which vertical cross-section is in the form of a 4-sided polygon in which an upper side and a lower side are parallel and have a different length,
- and wherein the length of the lower side for shapes I) and III), or the length of a flat part of the concave plane in shape II) ranges from 0.1 μm to 20 μm,
- and wherein a distance between each element in the film ranges from 1 μm to 20 μm,
- and wherein a height of each element is lower than 7 μm.
