The method of forming a surface layer on a substrate is accomplished by dendrimerizing a mixture of branched monomers on the substrate surface wherein the monomers have heterogeneous functionalized branches and homogeneous connectivity to the substrate. A cascade polymer coated substrate is formed consisting essentially of a substrate including a surface and at least one dendrimerized surface layer consisting of heterogeneous functionalities, the layer being linked to the substrate by homogenous linkages preferably isocyanate linkages.

L'invention se rapporte à un procédé de formation d'une couche superficielle d'un substrat, qui consiste à dendrimériser un mélange de monomères ramifiés sur la surface du substrat. Les monomères ont des ramifications fonctionnalisées hétérogènes et une connectivité homogène, une fois appliqués sur le substrat. Un substrat revêtu de polymères en cascade est composé essentiellement d'un substrat comprenant une surface et d'au moins une couche superficielle dendrimérisée constituée de fonctionnalités hétérogènes, ladite couche étant liée au substrat par des liaisons homogènes, de préférence des liaisons isocyanate.
