A series of novel organic-inorganic hybrid membranes assembled by side-chain type sulfonated poly(arylene ether ketone sulfone) with amino groups (Am-SPAEKS-DBS) and ZIF-67 were prepared. Am-SPAEKS-DBS containing double bonds was synthesized by condensation polymerization, and the AMPS was grafted onto the main chain by post sulfonation. ZIF-67 was prepared by an ordinary solvent method. The structures of ZIF-67, Am-SPAEKS-DBS, and hybrid membranes were analyzed by proton nuclear magnetic resonance ( 1 H NMR), scanning electron microscopy (SEM), powder X-ray diffraction (PXRD) and Fourier transform infrared (FT-IR). All hybrid membranes had good dimensional stability and excellent oxidation stability. In addition, the swelling ratios of all hybrid membranes were low (<17.46%) at even 100 C, and the oxidative stability was higher than 92%. The proton conductivities of this series of membranes were much higher (0.0540.069 S cm À1 at 30 C, 0.088-0.116 S cm À1 at 80 C) than pure membrane (0.038 S cm À1 at 30 C, 0.076 S cm À1 at 80 C).The experimental results exhibited that the comprehensive properties of hybrid membranes are good, and hybrid membranes had substantially possible as proton exchange membranes. Highlights• Metal-organic frameworks were anchored on side-chain type organic polymer backbone.• The hybrid PEMs showed good dimensional stability and excellent oxidation stability.• The imidazole as a ligand in ZIF-67 contributes a part of the dissociated protons. K E Y W O R D Sorganic-inorganic hybrid membranes, proton conductivities, side-chains, sulfonated poly(arylene ether ketone sulfone), ZIF-67 Mengchi Ju and Qingyuan Shi contributed equally to this work.

“…The sizes of metal clusters range from 1 to 10 nm. 104 Organic− inorganic nanocomposites are employed in polymer electrolyte membranes (PEM), which are composed of nanosized inorganic building components in organic polymers. This design has allowed the desirable features of an inorganic backbone that is mechanically and thermally robust, as well as the ductility, flexibility, and processability of the organic polymer, to be combined in a single solid.…”

In recent years, organic and inorganic contaminants in wastewater (heavy metals, halides, nutrients, dyes, and pathogenrelated water pollution) have become a major global problem. There were initially fewer toxins, but as a result of fast industrialization and other human activities, they have rapidly risen. In addition to producing a host of health problems and organ system failure in people, these toxins have had a disastrous effect on the ecological balance of plants, animals, and even microbes. On the basis of nanotechnology, several methods for decontaminating water that use nanoadsorbents and/or photocatalysts are being researched. Due to their improved physical and chemical characteristics, several research studies have focused on the elimination of organic and inorganic pollutants using ferritesupported nanocomposite polymers as possible affordable substitutes for currently employed materials. In this review, the toxicity of heavy metals and the different adsorption capabilities of metal-doped ferrites, which are employed to detect the pollutants in wastewater, are discussed in detail. Also, it provides various synthesis methods to produce ferrite-supported polymer-based nanocomposites and a current review of them with a special emphasis on their exceptional ability to remove organic and inorganic pollutants from wastewater. As a result, ferrite-supported polymer-based nanocomposites, which are also less expensive and swellable, can act as effective adsorbents for the removal of both organic and inorganic pollutants. It has outstanding performance for sizes between 10 and 30 nm.

“…Moreover, the framework of MOF-801-Zr with a large number of hydrophilic units (COOH and −OH) not only gives MOF-801-Zr a high H 2 O absorption capacity but also promotes interface compatibility between the filler and polymer matrix. Sequentially, several kinds of MOF-801-Zr -based composite films with high σ values have been prepared. − …”

Hafnium (Hf)-based UiO-66 series metal−organic frameworks (MOFs) have been widely studied on gas storage, gas separation, reduction reaction, and other aspects since they were first prepared in 2012, but there are few studies on proton conductivity. In this work, one Hf-based MOF, Hf-UiO-66-fum showing UiO-66 structure, also known as MOF-801-Hf, was synthesized at room temperature using cheap fumaric acid as the bridging ligand, and then imidazole units were successfully introduced into MOF-801-Hf to obatin a doped product,
