Abstract

Polymer complex membranes containing AgNO₃ dissolved in a polymeric solvent do not exhibit facilitated olefin transport in the solid state due to strong interaction between the silver ion and its counteranion. However, we successfully made AgNO₃ as an active olefin carrier upon incorporation of positively charged polypyrrole (PPy) into a polymer solvent such as poly(N-vinylpyrrolidone) (PVP) or poly(2-ethyl-2-oxazoline) (POZ). Upon addition of positively charged PPy into polymer/AgNO₃ complex membranes, the interaction of the silver cation with the nitrate anion was weakened because of nitrate anion complexation by positively charged PPy. This was confirmed by FT-IR and X-ray photoelectron spectroscopy. The enhanced carrier activity of AgNO₃ in PVP or POZ with PPy is attributable to complexation of NO₃^- with positively charged PPy, which led to a weak interaction between Ag⁺ and NO₃^-.
