WebbPassivation of the silver nanowires in solution before mixing with PEDOT:PSS was attempted using two small molecules, MuA and MBI. However, the performance of electochromic devices using these passivated nanowires was poor due to nanowire clumping. Alternative suggestions for passivating silver nanowire surfaces in solution … Webbpassivity and passivation. Metals passivate because of the formation of an intervening oxide film which is protective, and which form as a direct consequence of the oxidation reaction. Not all oxides formed on the surface passivate the metal however, and detailed understanding of this is necessary. The ability for an oxide which forms
