“…This means that the TNTs clusters exist in hybrid materials. Hydroxyl (–OH) groups on the TNTs surface could easily react with Si(OH) 3 generated from the hydrolysis of KH-550 to form Si–O–TNTs via a classic condensation reaction [14,41]. Therefore, the TNTs were grafted onto the side chain of the polymer matrix through the silane coupling agent, KH-550, as a bridge.…”

A series of novel self-cleaning hybrid photocatalytic ultrafiltration (UF) membranes were fabricated to separate polyacrylamide, which is widely used as a commercial flocculant. To maximize the self-cleaning and anti-fouling properties of hybrid membranes, high surface area TiO2 nanotubes (TNTs) with excellent photocatalytic activity were homogeneously introduced into a poly(aryl ether sulfone) matrix by chemical bonds. The chemical structure, micromorphology, hydrophilicity, separation efficiency, fouling behavior, and self-cleaning property of the prepared hybrid membranes were well characterized and evaluated. For the optimal sample, the flux recovery ratio increased from ~40% to ~80% after simulated sunlight irradiation for 20 min, which was attributable to the homogeneous dispersion and efficient photocatalytic degradation ability of TNTs. Furthermore, the intelligent fabrication strategy enhanced the anti-aging ability of the hybrid membranes via the use of a fluorine-containing poly matrix. This work provided new insight into the fabrication of high-performance self-cleaning inorganic/organic hybrid membranes.

“…The authors claimed that this hybrid membrane could be applicable for low-temperature fuel cells. Ren et al [133] fabricated SPAES/SiO 2 hybrid membranes by then reaction 3-isocyanatopropyl) triethoxysilane (ICPTES) with tetraethoxysilane (TEOS). A series of novel organic–inorganic hybrid proton exchange membranes were prepared from sulfonated poly arylene ether sulfone Am-SPAES/SiO 2 hybrid membranes showed that the proton conductivities, methanol permeability and water uptake increase with increasing the content of SiO 2 (3, 6 and 10 wt %).…”

A Review on Sulfonated Polymer Composite/Organic-Inorganic Hybrid Membranes to Address Methanol Barrier Issue for Methanol Fuel Cells

This paper focuses on a literature analysis and review of sulfonated polymer (s-Poly) composites, sulfonated organic, inorganic, and organic–inorganic hybrid membranes for polymer electrolyte membrane fuel cell (PEM) systems, particularly for methanol fuel cell applications. In this review, we focused mainly on the detailed analysis of the distinct segment of s-Poly composites/organic–inorganic hybrid membranes, the relationship between composite/organic– inorganic materials, structure, and performance. The ion exchange membrane, their size distribution and interfacial adhesion between the s-Poly composites, nanofillers, and functionalized nanofillers are also discussed. The paper emphasizes the enhancement of the s-Poly composites/organic–inorganic hybrid membrane properties such as low electronic conductivity, high proton conductivity, high mechanical properties, thermal stability, and water uptake are evaluated and compared with commercially available Nafion® membrane.

“…The addition of a large amount of filler leads to a relative decrease in the density of the sulfonate ion clusters, which is obviously disadvantageous for proton conduction and the proton transportation network. 1,45 The activation energy (E a ) of the proton conductivity for each membrane was estimated from the Arrhenius equation as shown in Figure 12(b). The E a for the composite membranes was lower than that of the SPTES membrane.…”

In this article, novel nanocomposite proton exchange membranes (PEMs) were prepared by embedding imino-containing phosphorylated silica nanoparticles into a sulfonated poly(arylene thioether sulfone) (SPTES) polymer matrix. SPTES was synthesized via condensation polymerization of 4,4′-thiobisbenzenethiol, 4,4′-difluorodiphenylsulfone, and disodium 3,3′-disulfonate-4,4′-difluorodiphenylsulfone. The imino-containing phosphorylated silica particles (Si-imP) were prepared by the Kabachnik–Fields reaction, which is confirmed by scanning electron microscopy, Fourier-transform infrared spectroscopy, and energy dispersive spectroscopy. The results showed that the Si-imP were uniformly distributed in the composite membrane. The properties of the composite membranes, including thermal stability, water uptake, swelling ratio, oxidative stability, and proton conductivity, were thoroughly evaluated. Experimental results indicated that Si-imP may be effective reinforcement materials for SPTES membranes. It is noteworthy that an increase in proton conductivity from 0.138 S cm−1 of the SPTES control membrane to 0.173 S cm−1 of the composite membrane was achieved at the Si-imP content of 5 wt% under fully hydrated conditions at 80°C. This finding primarily stems from the fact that the Si-imP could be linked with the sulfonate ion clusters of SPTES to form more continuous ionic networks. These networks act as efficient proton-hopping pathways to enhanced proton conductivity. The nanocomposite membranes are demonstrated to be promising candidates as new polymeric electrolyte materials for PEM fuel cells operated at medium temperatures.
