Transport properties and ion binding in aqueous solutions of alkaline salts of poly(thiophen-3-ylacetic acid)

Popis výsledku v původním jazyce

Aqueous solutions of poly(thiophen-3-ylacetic acid) neutralized with LiOH, NaOH, and CsOH were for the first time investigated using conductivity measurements (in concentrations, c, ranging from 2.10(-5) to 8.10(-2) mol/dm(3) and temperatures from 278.15to 313.15 K), transport number measurements (at 298.15 K) and osmotic coefficient measurements using vapor pressure osmometry (at 313.15 K) and cryoscopy, in order to identify essential electrochemical characteristics of this conjugated polyelectrolyte.The measurements of the polyion constituent transport number data suggested that a fraction of counterions traveled associated with polyions. The fraction of "free" counterions, determined from the transport measurements by the association theory of Huizenga, Grieger, and Wall was around 0.5, which is in good agreement with the osmotic coefficient data. Neither the fraction of "free" counterions, nor the osmotic coefficient significantly depends on the nature of the counterion species.
