Also, a vehicle with at least one such self-cleaning aerodynamic surface.

Rubber compositions comprising an epoxide diene elastomer and a cross-linking system

A rubber composition contains: an elastomer matrix comprising at least one diene elastomer comprising epoxide functions, at least one reinforcing filler, and a system for crosslinking said polymer, comprising at least one organopolyphosphorus compound of general formula (I) in which A represents a covalent bond or a hydrocarbon group comprising at least 1 carbon atom, which is optionally substituted and which optionally comprises one or more heteroatoms, and the Rs represent, independently of one another, a hydrocarbon group comprising at least 1 carbon atom or a hydrogen atom.

Couche externe autonettoyante comprenant une surface aérodynamique autonettoyante et véhicule comprenant ladite couche externe

L'invention a pour objet une couche externe (22) autonettoyante comprenant une surface aérodynamique (S) autonettoyante, configurée pour extraire au moins une partie de l'oxygène présent dans l'atmosphère (A) en contact avec la surface aérodynamique (S), afin de priver au moins partiellement d'oxygène l'hémolymphe des résidus d'insectes (24) présents sur la surface aérodynamique (S) suite à des impacts d'insectes. Ainsi, l'hémolymphe reste plus longtemps dans un état liquide ou pâteux facilitant le détachement des résidus d'insectes (24) de la surface aérodynamique (S). L'invention a également pour objet un véhicule comprenant au moins une telle surface aérodynamique autonettoyante.
