A surface 2 which comprises a plurality of protrusions 4, each protrusion 4 being formed from a base portion 6 projecting away from the plane of the surface 2 and an extending portion 8 which lies in a direction which has a component parallel to the plane of the surface 2. The protrusions 4 are 0.25-100 microns long and 0.1-1.5 microns wide. The protrusions 4 are identical and all lie in the same direction. In some embodiments the extending portions 8 lie above the surface 2 while in others the extending portions 8 contact the surface 2. The protrusions 4 can be substantially rigid and comprise a hydrophobic material. The surface 2 can be a fibre, footwear, a garment or the inside of a container. The protrusions 4 can be made by stamping, deposition, self assembly, moulding or removal of material. The surface 2 can provide a self-cleaning, mud-shedding, anti-fouling or super hydrophobic properties. |
