“…Hence, ion transport through an electrolyte polymer membrane plays a vital task to enhance the efficacy of a fuel cell. 45 Conductivity measurements were taken in order to assess the ionic liquid encapsulation in Cu-NDC particles that have an effect on the polymer membranes (Figure 6). The bulk resistance values taken from the Nyquist impedance plot and proton conductivity values were calculated.…”

Ionic liquid (1-methyl-3-propylimidazolium iodide) (L) encapsulated in a copper-established metal organic framework (M) was synthesized using 2,6-napthalene dicarboxylic acid as the organic linker. The prepared additive was incorporated into a sulfonated polystyrene-blockpoly(ethylene-ranbutylene)-block-polystyrene (S-PSEBS) polymer. Thermal and chemical stabilities of the altered membranes were used to investigate the effect of the ionic liquid in S-PSEBS/ML composites. The physicochemical features of the membranes were investigated in depth in order to determine their appropriateness for fuel cell applications. Tensile strengths of the prepared composites were found to be between 18 and 25 MPa. The S-PSEBS/ML1:3 membrane exhibited the highest proton conductivity of 0.0310 S cm −1 ; however, the S-PSEBS was restricted to 0.0165 S cm −1 . The incorporation of ML into an S-PSEBS increased both proton conductivity and oxidative stability. Hence, the reported S-PSEBS/ML membranes are feasible materials to be used in PEMFC as alternate electrolytes.

“…Many researchers used carbon as one of main source for blending with SPEEK because of its reduction in methanol cross over, good mechanical and thermal stability. Sivasubrmanian et al 59 Please do not adjust margins Please do not adjust margins reported SPEEK membrane doped with single-walled CNT (SWCNT) and fly ash (FA) by post sulfonation method, they prepared SPEEK (DS 65%) and incorporated with SWCNT and FA by solution casting method. Incorporation of SWCNT/FA into SPEEK enhanced the water uptake and mechanical properties, but the reduction in IEC was noticed.…”

“…In order to reduce the use of non‐biodegradable plastics, high concentration of inorganic fillers were physically blended into thermoplastic polymers (polyethylene terephthalate, polypropylene, polyurethane) 11‐14 . These fillers are usually minerals, such as fly ash, 15 silica fume, 16 slag, 17 and so on, which are rich and abundant in nature. The produced composites exhibited high resistance to heat or chemicals.…”

High fraction of inorganic compounds filled polymer composites with lightweight character show a potential application on building and transportation. In this study, super‐high fraction of organic montmorillonite (OMMT>30%) filled Polyamide 6 (PA6) foams were prepared via a solution foaming. The influence of OMMT content on structures and properties of foams was studied. When the OMMT content was higher than 50%, the surface of cells turned from smooth to nest‐like appearance. The addition of excessive clay depressed the crystalline behavior of PA6 during foaming. However, it did not damage the compressive mechanical properties of foams. PA6 macromolecules played a role of binder, endowing interfacial strength and structural integrity of cell walls. With the increase of OMMT loading content from 33% to 75%, the composite foams showed an increased specific moduli from 2.8 to 4.1 MPa. The current work realized a facile processing of polymer foams with high loading of fillers. The corresponding filler dominant lightweight products open the door to a wide range of potential applications to reduce the use of non‐biodegradable plastics.
