Abstract: front page image
(EN)A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.
(FR)L'invention concerne une surface glissante autoréparatrice résistant au grattage qui est préparée par l'action capillaire sur un revêtement liquide chimiquement inerte à haute densité sur une surface solide râpeuse présentant des topographies à nano- et micro-échelle. Cette surface glissante présente des propriétés anti-mouillage et manifeste une réduction sensible d'adhérence d'une vaste gamme de matériaux biologiques, y compris des particules en suspension ou en solution. Plus particulièrement, les surfaces glissantes peuvent s'utiliser dans des dispositifs et des équipements médicaux pour repousser efficacement des matériaux biologiques tels que le sang et pour prévenir, réduire ou retarder la coagulation et la formation de caillots impliquant des surfaces. En outre, les surfaces glissantes peuvent s'utiliser dans la prévention de salissement par des micro-organismes tels que les bactéries.
