Influence of plasticizers on ion-selective polyimide membranes

Abstract

Polyimide-based membranes containing calcium synthetic ionophores and different type plasticizers were characterized in terms of surface morphology, glass transition temperature (Tg), a. c. impedance, and thermo gravimetric behaviour. The study aimed to identify correlations between structural parameters and ion-selective performances of polyimide when introduced in macro and micro ion-selective devices.
