Abstract：An original strategy for self-assembling silver nanowires through evaporation of an emulsion with certain prescription at room temperature was explored in this report. Some organic solvents with low boiling points, such as chloroform and benzene, and nonionic surfactants were found to favor to form a uniformity silver-nanowire network with honeycomb-like architecture. Polystyrene is an important ingredient in emulsion solutions. In the evaporation process of an emulsion solution, polystyrene is firstly precipitated from the organic phase in the emulsion, and hinders silver nanowires movement to aggregate together on the glass surface in this process. The best prescription of this method is about 29%, 3% and 68% (for volume ratio), for organic solvent, nonionic surfactant and water respectively, maintaining the concentration of polystyrene at about 0.14g/ml. The strategy for obtaining this kind of silver-nanowire architecture on a glass slice in this report might be a key progress for stretchable, conductive and transparent electronic materials.
