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- English AMER CHEMICAL SOC ION-EXCHANGE MEMBRANES DENSITY-FUNCTIONAL THEORY ELECTROLYTES PROPYLENE BEHAVIOR SALTS COORDINATION PERMEATION SEPARATION MECHANISM Revelation of facilitated olefin transport through silver-polymer complex membranes using anion complexation Article 10.1021/ma0340210 1 MACROMOLECULES, v.36, no.12, pp.4577 - 4581 MACROMOLECULES 36 12 4577 4581 scie scopus 000183526900045 2-s2.0-0038272073 Polymer Science Polymer Science Article ION-EXCHANGE MEMBRANES DENSITY-FUNCTIONAL THEORY ELECTROLYTES PROPYLENE BEHAVIOR SALTS COORDINATION PERMEATION SEPARATION MECHANISM
