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. |
