Synthesis and characterization of composite membranes based on α-zirconium phosphate and silicotungstic acid

Nafion®–sepiolite composite membranes for improved proton exchange membrane fuel cell performance

“…Non-fluorinated polymers such as PEEK [4,5,6], PSU [7,8] or PBI [9,10,11,12] and their sulfonated counterparts have been extensively studied as alternatives. Another strategy consists in incorporating inorganic fillers such as metal oxides [13,14,15,16,17,18,19,20,21], acids [22,23,24,25,26], phosphates or phosphonates [27,28,29] into the Nafion® matrix to make the composite or hybrid membrane more mechanically stable, less permeable to reactant and more hygroscopic. Different clays, montmorillonite [30,31,32] or laponite [33] for instance, have also been evaluated as possible fillers.…”

Sorption and pervaporation results of clinoptilolite filled poly(vinylalcohol) membrane prepared for dehydration of aqueous organic mixtures

“…This confirms that thermal stability of the composite mainly depends on the addition of zeolite. [23,36,37] As a result, the PVA-2 membrane is a little more stable than the PVA-1 membrane although there is no significant difference between PVA-1 and PVA-2 membranes. The SEM cross-section micrographs of the PVA-2 membrane indicate that the zeolite particles are uniformly distributed in the PVA matrix ( Figure 5).…”
