摘要： The present invention is directed to a process for the preparation of an aqueous dispersion of coacervates having a core-shell structure, the core (a) being an inorganic particle being anionic or cationic and the shell (b) being a copolymer wherein said copolymer comprises at least two parts, A and B, part A being cationic if particle (a) is anionic, and anionic if particle (a) is cationic, and part B being neutral in pH conditions of said dispersion. More particularly, the invention is directed to treating compositions comprising that aqueous dispersion of coacervates delivering antifouling, water sheeting, antisoiling, anti-adhesion, adhesion, anti-deposition, and/or anti-UV properties onto all kinds of surfaces.

摘要： 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.
