- New SPEEK Membranes Modified with Bisphophonate Dopants [Resumo]Publication . Teixeira, Fatima; Teixeira, António Paulo Silva; Rangel, Carmen M.ABSTRACT: ustainable emerging energy technologies are pivotal to a decarbonized society that still continuously increases its energy demands. Fuel cells and eletrolyzers are part of these promising sustainable technologies, but they still depend on several factors, especially on their membranes. These are a key component acting as a separator, between their different materials and electrolytes of different devices' compartments, and as a selective ion-exchange barrier, controlling the ion flow and species permeability. Sulfonated poly(etheretherketone) (SPEEK) polymer is a versatile non-fluorinated alternative, as a low-cost and more environmentally friendly membrane, to the most commercially successful membrane based on the perfluorinated sulfonic Nafion®. Also, our previous studies showed that the incorporation of BPs dopants into the polymeric matrices, modifies the properties of the doped membranes, including their proton conduction and durability.
