A surface (30) suitable for promoting the formation of droplets of liquid (35) is provided comprising alternating regions of liquid repelling (32) and liquid attracting (33) material in at least one direction across the surface wherein the diameter of the droplets is controlled by the size of the smallest dimension of the liquid attracting material. The surface (30) may be textured and/or form a pattern. Also disclosed are a method and a system of collecting a liquid (35) carried by or condensed out of a vapour comprising passing a vapour across such a surface (30) and a method of purifying a liquid by passing a vapour containing droplets of a liquid over such a surface.
L'invention concerne une surface (30) appropriée pour favoriser la formation de gouttelettes de liquide (35), qui comprend en alternance des régions de matière repoussant (32) et attirant (33) le liquide dans au moins une direction sur la surface. Le diamètre des gouttelettes est régulé par la taille de la plus petite dimension de la matière attirant le liquide. La surface (30) peut être texturée et/ou former un motif. L'invention concerne également un procédé et un système de collecte de liquide (35) transporté par, ou condensé d'une vapeur sur ladite surface (30), ainsi qu'un procédé permettant de purifier un liquide en faisant passer une vapeur contenant des gouttelettes de liquide sur ladite surface.
