Abstract
This invention relates to a fibrillar microstructure and processes for the manufacture thereof. These processes involve micromachining and molding, and can prepare sub-micron dimensioned fibrillar microstructures of any shape from polymeric as well as other materials.
Claims12
A fibrillar microstructure which is prepared from a flowable microstructure material, said fibrillar microstructure comprising (a) a foundation, (b) a plurality of first-tier fibrils, each of which is attached at a first end to the foundation, and (c) a plurality of second-tier fibrils, each of which is attached to a second end of a first-tier fibril;
- wherein each first-tier fibril has a cross-sectional shape that is selected from the group consisting of elliptical and polygonal;
- and
- wherein each second-tier fibril has a cross-sectional shape that is selected from the group consisting of elliptical or polygonal but that is different from the cross-sectional shape of the first-tier fibril to which it is attached.
