Abstract:
The invention relates to an article with enhanced hydrophobic and/or icephobic surface properties comprising a substrate and a coating composition deposited onto the surface of said substrate, said coating composition comprising (i) one or more crosslinked polyurethane polymers and (ii) particulates of precipitated silica functionalized with a linear polyfluorinated compound presenting at least one α,ω alcoxysilane end group, said functionalized silica particulates being either embedded inside the crosslinked polyurethane polymers or deposited onto the outside surface of a separate layer of said crosslinked polyurethane polymers. The invention also relates to a method to prepare such article, and to the functionalized precipitated silica particulates used therein.

Abstract:
La présente invention concerne un procédé permettant de réaliser un revêtement à base de deux composés organiques semi-conducteur C P et C N , respectivement de type P et de type N, C N étant immiscible au composé C P dans le revêtement réalisé, et où : (A) on dépose sur la surface du support une solution comprenant les composés C P et C N dans un milieu solvant S capable de solvater les composés C P et C N sans réagir chimiquement avec ceux-ci, ledit solvant S étant constitué par un mélange de : une première fraction constituée d'un solvant ou mélange de solvants S1 capable de solvater les deux composés C P ou C N ; et une seconde fraction, miscible à la première fraction, constituée d'un solvant ou mélange de solvants S2 qui a un point d'ébullition supérieur à celui du solvant ou mélange de solvants S1 et qui est capable de solvater sélectivement un des composés C P ou C N mais non l'autre; et (B) on élimine par évaporation le solvant S présent dans le dépôt ainsi réalisé.
Abstract:

Abstract:
A co-assembly method includes, in an aqueous polyelectrolyte composition comprising: (a) a first polyelectrolyte dispersed in the composition and having a net electric charge of a first polarity, (b)a second polyelectrolyte dispersed in the composition and having a net electric charge of a second polarity, wherein the second polarity is opposite the first polarity, and (c)an electrolyte dissolved in the composition in a concentration effective to prevent co-assembly of the polyelectrolytes, the step of allowing co- assembly of the polyelectrolytes by: (1) decreasing the concentration of the electrolyte, or (2) forming an interface between the aqueous polyelectrolyte composition and a surface of a solid substrate or of a second liquid phase, wherein the surface has an affinity for at least one of the polyelectrolytes, or (3) decreasing the concentration of the electrolyte and forming such an interface.
