“…The same behavior was observed for the Nafion®/zeolite composite membranes, with zeolite ranging from 0 to 12.5 wt.‐%. The water uptake increased with the increase of the amount of zeolite, ranging from 32.3 to 45.2 % at ambient temperature …”

Sulfonated poly(ether ether ketone) (SPEEK)/zeolite/ionic‐liquid composite membranes were prepared with different amounts of 1‐butyl‐3‐methylimidazolium trifluoromethanesulfonate ([C4MI]CF3SO3) or 1‐decyl‐3‐methylimidazolium trifluoromethanesulfonate ([C10MI]CF3SO3) ionic liquids (ILs). The structure of the composite membranes was investigated by FTIR‐ATR spectroscopy, X‐ray diffraction, atomic force microscopy, and by thermogravimetric analyses. The introduction of the IL, encapsulated in zeolite, into the SPEEK polymer leads to improvement of the water uptake, thermal stability, and proton conductivity of the composite membranes, compared with pristine SPEEK. The proton conductivity of the membranes with 1.5 % and 2.0 % [C4MI]CF3SO3 IL showed values of 3.34 mS cm–1 and 5.98 mS cm–1, respectively, under anhydrous conditions at 80 °C. The conductivity obtained for these membranes is about 100 times higher than for pristine SPEEK (0.038 mS cm–1).

“…Recently, Devrim and Albostan (2015) modified Nafion ® membranes with zeolit by solvent casting procedure; the modified membranes demonstrated increasing water uptake and proton conductivity owing to the water retention properties of the zeolite and interaction between the Nafion ® polymer and zeolite particles. In another study, Auimviriyavat et al (2011) reported ferrierite zeolite as inorganic filler in SPEEK membrane.…”

“…4,5 Therefore, researchers are studying new PEM materials that can replace Nafion. [6][7][8] Sulfonated aromatic polymers, such as poly(aryl ether ketone) (PAEK), poly(ether ether ketone) (PEEK), poly(ether ether ketone ketone) (PEEKK), polyimides and poly(arylethers), are easily sulfonated and modified; moreover, they possess excellent chemical resistance, high thermo-oxidative stability, and good mechanical properties. [9][10][11][12] Thus, sulfonated PAEKs (sPAEKs) are promising PEM materials for Nafion replacement.…”

Study on proton exchange membrane (PEM) with the aim toward excellent battery performance of PEM for fuel cells has attracted increasing attention. In this work, nanocellulose (CNC) aminated by KH792 noted as NN was prepared. CNC or NN/sulfophenylated poly(ether ether ketone ketone) (sPEEKK) nanocomposite membrane (SN) or (SNN) were produced by solution mixing. SNN was further coated with tetraethyl orthosilicate (TEOS) to obtain SNNT. The properties of sPEEKK, SN, SNN, and SNNT membranes were thoroughly investigated. The proton conductivity of SN4 was 0.22 S·cm−1 at 90 °C, while a proton conductivity of 0.30 S·cm−1 was obtained for SNN4, and an even higher value of 0.36 S·cm−1 at 90 °C was obtained for the TEOS‐coated SNN4 (SNN4T). Meanwhile, SNN4T showed high thermal stability, and its Td5 was as high as 318.2 °C. Furthermore, the composite membrane coated with TEOS also presented excellent oxidative stability. The mass of SNN2T after treated in Fenton agent for 1 h at 80 °C was still retained 96.2%, and it was not fully dissolved until 11 h. It was illustrated that aminated CNC/sPEEKK nanocomposite membranes coated with TEOS is a kind of promising materials as PEMs for fuel cells. © 2019 Wiley Periodicals, Inc. J. Polym.
