PROBLEM TO BE SOLVED: To provide an article having an antifouling surface incorporating a texture designed to provide resistance to water and oil. SOLUTION: The article 10 comprising the antifouling surface 12 is provided. The surface 12 comprises a material having a nominal liquid wettability sufficient to generate, with reference to an oil, a nominal contact angle of at least about 30 degrees; and a texture comprising a plurality of features 16 disposed on the surface. The features 16 have a size, shape, and orientation selected such that the surface 12 has an effective wettability sufficient to generate, with reference to an oil, an effective contact angle greater than the nominal contact angle. The features 16 comprise a height dimension 20(h), a width dimension (a), and a spacing dimension (b) such that, ratio b/a is less than about 4, and ratio h/a is less than about 10.
