The present invention generally includes a) a substrate comprising a substrate surface, and b) a polymer layer comprising a polymer layer surface, the polymer layer comprising i) a polymer, and ii) at least a portion of the substrate surface and the substrate. A polymer layer surface comprising a first region and a further region, the wetting angle for water wetting of the first region and the water wetting of the further region For composites, the absolute value of the difference from the wetting angle is at least about 10 °.
