Techniques for PBI membrane characterization

Abstract

The chapter describes common methods for membrane characterization. While it does not go into theoretical depths, general explanations, limitations, practical notes, and critical comments are provided. Covered methods include determination of water uptake and acid doping level, measurement of proton conductivity, molecular weight analysis by viscosity and size exclusion chromatography, determination of solubility and gel content, filtration of polymer solutions, characterization of mechanical properties (tensile testing, compression and creep tests, dynamic mechanical analysis), permeability of hydrogen and methanol and electroosmotic drag of water as well as definition and control of humidity. ？ Springer International Publishing Switzerland 2016.
