Transport properties of poly(2,6-dimethyl-1,4-phenylenoxide) membranes at different degrees of sulphonation

Popis výsledku v původním jazyce

A variety of functionalised polymeric materials have been studied during the last decade with respect to theirs possible utilisation as a solid polymer electrolyte in fuel cells. The typical representatives of these membranes are perfluorosulphonate polymers, such as Nafion. Regardless of its high proton conductivity, mechanical and chemical stability, Nafion also has serious disadvantages (high production costs, relatively high permeability to methanol, sensitivity to the water management). In this study the new type of ion?exchange membrane based on the sulphonated poly(2,6?dimethyl?1,4-phenyleneoxide) (SPPO) has been prepared. This polymer is an attractive material for the preparation of membranes because it possesses excellent film- and membrane-forming properties as well as high thermal and chemical stability. Aim of this study was to determine influence of degree of sulphonation of SPPO on the kinetics of its swelling in the water vapour and mass transfer properties. Ion conducti
