Structural characterisation of a new sulfonate functionalised polyamide in high temperature fuel cell applications

Polyamides form a class of polymers with exceptional performance for a wide range of functional applications. Their properties can be readily customized by inducing morphological changes through alterations in the synthesis process or conditions, and by incorporating flexible groups into the polymer backbone. Fully aromatic polyamides that have excellent high-temperature stability combined with tunable physical and chemical properties are increasingly used for a range of industrial applications. Here, we will first study the structures of polyamide reverse osmosis membranes generated via liquid-liquid and liquid-aerosol assembly. Secondly, we will then look at the functionalised polyamide membrane as a high-temperature proton exchange membrane The results will allow us to unravel the optimal approach as well as chemical and morphological factors essential to advance the design of high-performance membranes for energy applications.
