Disclosed herein is a method of forming a bioadhesion resistant article comprising extruding a material through a die bearing a pattern of protrusions such that the extruded material has a surface having a series of parallel splines above a base surface, and applying pressure with a first patterned template to the surface of the extruded material such that the series of parallel raised splines are formed into discrete raised segments of varying length; where the patterned template comprises grooves that are inclined at an angle α to the splines. The method further comprises applying pressure with a second patterned template to the surface of the extruded material, where the second patterned template contains grooves that are inclined at an angle ß to the splines.

    L'invention concerne un procédé de formation d'un article résistant à la bioadhérence comprenant l'extrusion d'un matériau à travers une filière portant un motif de saillies de sorte que le matériau extrudé ait une surface ayant une série de cannelures parallèles au-dessus d'une surface de base et l'application d'une pression avec un premier gabarit à motifs sur la surface du matériau extrudé de sorte que la série de cannelures en relief parallèles soient formées en segments en relief discrets de longueur variable ; le gabarit à motifs comprenant des rainures qui sont inclinées selon un angle α par rapport aux cannelures. Le procédé comprend en outre l'application de pression avec un deuxième gabarit à motifs sur la surface du matériau extrudé, le deuxième gabarit à motifs contenant des rainures qui sont inclinées selon un angle ß par rapport aux cannelures.
