The sodium superionic conductor structure (NASICON) Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is a promising active filler for its high ionic conductivity and air stability. Nonetheless, its large-scale application remains limited by chemical instability with lithium anodes. Herein, a novel poly(vinylidene fluoride- co -hexafluoropropylene) (PVDF-HFP)-based composite polymer electrolyte (CPE), designated as PPALx-D, is synthesized via a blade-casting method. This CPE comprises a conductive poly(poly(ethylene gly co l) methyl ether methacrylate-co-(lithium 2-acrylamido-2-methylpropanesulfonic acid)) (P(PEGMEMA-co-AMPSLi)) matrix, inorganic LATP filler, and an in-situ polymerized 1,3-dioxolane (DOL) artificial interlayer. The physicochemical and electrochemical properties of the as-prepared CPEs are systematically characterized. Results show that the PPAL5-D CPE, despite being thinner and containing less liquid electrolyte, provides faster organic-inorganic Li + transport channels and exhibits superior electrochemical compatibility with Li metal anodes. The PPAL5-D CPE achieves a high room-temperature (RT) ionic conductivity of 3.47× 10 −4 S cm −1 and a high Li + transference number of 0.61. The assembled LFP|PPAL5-D|Li battery demonstrates significantly improved cycling stability, delivering a discharge capacity of 131.5 mAh g −1 at 1C for 400 cycles at RT. This study proposes a feasible methodology for preparing organic-inorganic composite electrolytes, advancing the development of quasi-solid-state Li metal batteries (LMBs).

Preventing high-temperature oxidation and enhancing corrosion resistance are crucial factors influencing the quality of copper foil in lithium-ion batteries and their overall service life. The development of chromium-free antioxidation systems has gained significant attention due to their environmental advantages. In this study, we formulated an antioxidation liquid composed of polyvinyl alcohol (PVA), nano-silica(nano-SiO 2 ), and citric acid (CA), and applied it to copper foil using a chemical impregnation process. Various characterization techniques, including scanning electron microscopy (SEM), Tafel curves, X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and electrochemical impedance spectroscopy (EIS), were utilized to investigate the microstructure, antioxidation properties, and corrosion resistance of the treated copper foil. The results demonstrate that with a PVA concentration of 4 g/L, nano-SiO 2 concentration of 7 g/L, and CA concentration of 5 g/L, the treated copper foil exhibits excellent resistance to high-temperature oxidation and corrosion. Specifically, under conditions of 140℃ for 15 min, the surface of the copper foil remains largely unchanged, and the corrosion resistance efficiency can reaches 75.49 %. The study reveals a trend of cross-linking between PVA and CA, which rapidly forms a protective film on the copper foil surface. Nano-SiO 2 acts as a filler, mitigating defects and enhancing the density and robustness of the film. This chromium-free, environmentally friendly antioxidation process aligns with sustainable development principles and offers new insights for advancing chromium-free antioxidation technologies.

A thin inorganic composite membrane composed of 94 wt% Al 2 O 3 and 6 wt% styrene-butadiene rubber (SBR) polymer binder is prepared via an aqueous solution casting process. 1 wt% polyethylene glycol (PEG) is introduced into the casting suspension for the preparation of a 37 µm-thick inorganic composite separator. PEG plays a key role to enhance the stability of the casting suspension to separate the thin membrane from the substrate, and to increase the porosity of the membrane. The as-prepared Al 2 O 3 /SBR separator shows a superior thermal stability under 130 °C with no any shrinkage, higher electrolyte uptake/retention and ionic conductivity than the common polyethylene (PE) separator. In LiNi 1/3 Co 1/3 Mn 1/3 O 2 |graphite cells, the inorganic composite separator exhibits excellent cycling stability and good rate performance.

The corrosion of ancient bronze relics and protection measures after excavation are of great importance to the study of historical and cultural heritage. At present, the bionic superhydrophobic surface anticorrosive coating is one of the main anticorrosive measures of bronze cultural relics. It aims to construct a barrier to prevent the contact between corrosive media and bronze to reduce the invasion of corrosive media. However, due to structural defects such as micropores in a single organic coating, corrosive media (O2, Cl–, and H2O) can penetrate the coating to the metal matrix. Nanomaterials such as MXenes and metal–organic frameworks (MOFs) can fill structural defects such as microholes and microcracks of the coating, thereby improving the density of the coating. Therefore, to improve the performance of organic waterborne polyurethane (WPU) coatings with good chemical protection, nanomaterial ZIF-8/Ti3C2Tx was introduced based on the organic–inorganic hybrid theory. Finally, the coating was modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane, and the organic–inorganic composite coating was prepared. Characterizations of the composite coating were performed via Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller method, field-emission scanning electron microscopy/energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. Colorimetric measurements and reversibility experiments of the coating were also evidenced. According to the electrochemical impedance spectroscopy assessments, the |Z|0.01 Hz value of the F-WPU@ZIF-8/Ti3C2Tx composite coating in a 3.5 wt % NaCl solution, which was higher compared to other composite coatings. Moreover, the icorr value of the F-WPU@ZIF-8/Ti3C2Tx (3.344 × 10–6 A cm–2) composite coating is reduced by 2 orders of magnitude compared with F-WPU@ZIF-8 and F-WPU@Ti3C2Tx coatings. As a result, this organic–inorganic F-WPU@ZIF-8/Ti3C2Tx composite coating has good anticorrosion properties to bronze without causing an obvious color difference change and has potential application prospects in various metal material fields.

Polyacrylamide-montmorillonite organic-inorganic composites (poly[AM/O-MMT]) were synthesized by copolymerization of acrylamide (AM) on organic modified montmorillonite (O-MMT) using N , N -methylene-bis-acrylamide (MBA) as a crosslinker and ammonium persulfate (APS) as an initiator in an aqueous solution. The montmorillonite (MMT) was modified by methacryloyloxy ethyl dimethyl hexadecyl ammonium bromide (DMB) which was synthesized by 2-(dimethylamino) ethyl methacrylate with 1-bromohexadecane. The FTIR and XRD were used to verify the organification of MMT with DMB. The effects of the amount of the DMB and O-MMT on water absorption were studied. The swelling behavior in different saline solution and re-swelling ability in distilled water were investigated. The results showed that DMB and O-MMT content have an important effect on the water absorption of the composites. The addition of the DMB enhanced the salt resistance and delayed the swelling speed of the poly(AM/O-MMT). Simultaneously, the toughness was measured. The water blocking and profile control ability were evaluated by core physical simulation experiments. The results indicated that the poly(AM/O-MMT) has good plugging ability and profile control ability. The properties tested indicated that the poly(AM/O-MMT) has a promising prospect to be applied as a profile control or water shut-off agent for enhanced oil recovery in high salinity reservoirs.

Membrane distillation (MD), boasting high interception efficiency and low operational pressures, emerges as an innovative membrane technology. However, the occurrence of membrane fouling due to interaction between natural organic matter (NOM) and inorganic ions during the MD process curtails water purification efficiency, thereby constraining its potential applications. To address this quandary, this study integrates sulfate radical-based advanced oxidation processes (SR-AOPs) into MD technology to bolster membrane fouling control. A straightforward hydrothermal method coupled with vacuum filtration was employed to synthesize a Co 3 O 4 /Nitrogen-modified carbon quantum dots (NCDs)/PVDF (CN-PVDF) membrane for the first time, which was utilized in the MD treatment of simulated humic acid (HA) wastewater. Under visible light irradiation (1.9 kW/m 2 ), CN-PVDF membrane activation of peroxymonosulfate (PMS) effectively altered the chemical attributes of the MD feed solution and reduced organic matter concentration. Moreover, it dismantled the carboxyl sites on HA that interact with Ca 2+ , consequently attenuating the formation of organic–inorganic complex pollutants. The XDLVO analysis showcased that photo-Fenton oxidation led to a diminishment in pollutant hydrophobicity, correlating with a 17.59 kT reduction in pollutant-membrane adsorption and a 7.47 kT amplification in adhesion barriers. This strategy transformed the initial two-stage fouling mode into a singular one, which significantly decreased the flux decline and the fouling layer thickness. Furthermore, the CN-PVDF membrane demonstrated self-cleaning capabilities via photo-Fenton. This study advances an innovative approach to bolster the fouling resistance of MD membranes and provides substantial theoretical support for the integration of SR-AOPs and MD technologies.

Artificial photosynthesis is a promising way to change light energy into chemical energy stored in hydrogen peroxide (H 2 O 2 ). However, numerous heterojunction-based photocatalytic systems have substantially restricted effective H 2 O 2 generation due to the intrinsic tendency toward fast charge recombination and the deficiency in active site population on the catalyst surface, especially under conditions not employing sacrificial agents. This study in situ prepared ZnIn 2 S 4 (ZIS) nanoflowers onto a hollow covalent organic framework to strategically engineer a type-II organic–inorganic core–shell heterojunction photocatalyst, transforming O 2 into H 2 O 2 . The heterojunction photocatalyst exhibited an exceptional H 2 O 2 productivity of 3334μmol g −1 h −1 when no sacrificial agent was added, surpassing most reported systems. Mechanistic studies revealed that the heterojunctions extended the light absorption spectrum toward longer wavelengths and significantly increased the probability of electron transfer from photogenerated carriers to reactive species, which accelerated the reduction of O 2 to H 2 O 2 . Furthermore, theoretical calculations confirmed that the heterojunction formation modified the coordination environment of the active sites on ZIS, fine-tuned the binding interaction between O 2 and the catalyst interface, and reduced the energy barrier of intermediates, leading to superior performance. This study designed a novel, highly efficient organic–inorganic core–shell heterojunction photocatalyst and provided a promising strategy for enhancing the O 2 -to-H 2 O 2 conversion.

Lithium batteries have been widely used in various fields, however, further research needs to be conducted to improve their stability and long-term storage performance for the highly active lithium metal anode. Herein, an organic–inorganic composite film composed of polypropylene carbonate (PPC), lithium bis(trifluoromethanesulphonyl)imide (LiTFSI) and Li 6.5 La 3 Zr 1.5 Nb 0.5 O 12 (LLZNO) is fabricated on the lithium foil surface by spin-coating technique to passivate the lithium anode and regulate the ion transport behavior. The Li/CF x battery with the optimized composite film coated lithium anode exhibits excellent discharge capacity (1006.6 mAh/g, 0.1C) and high-rate capability (639.4 mAh/g, 5C), much higher than those of the uncoated Li/CF x battery. The discharge specific capacity remains 521.7 mAh/g at 0.1C after stored at 55 °C for 60 days, corresponding to a monthly self-discharge of 1.87 %, while the battery without coating film has almost failed. Theoretical calculation, Raman mapping and Kelvin probe force microscopy (KPFM) measurements demonstrate that the stable and ion-conductive composite film effectively increases ion channels, regulates ion migration and passivates the Li anode from the corrosion of liquid electrolyte during discharge and storage. Constructing a rational organic–inorganic composite film with high mechanical stability and ionic conductivity on the Li anode surface is a facile and cost-effective strategy to enhance the high-rate and long-term storage performance of Li/CF x battery.

Heat consumption is a serious energy waste, especially in an extremely cold environment. In view of their excellent advantages, several kinds of aerogels with different functions were emerged successively and served as critical materials in various areas. In this contribution, a simple strategy was developed to fabricate a high-fidelity and high-performance organic/inorganic composite aerogel by integrating dianhydrid-end capped polyamide acid (PAA) precursor and multi-amino functionalized hydroxyapatite (m-AmHA; used as the inorganic cross-linkers) in different feed ratios. Followed by the freeze-drying and thermal imidization treatments, the chemical cross-linked polyimide (PI) and HA based aerogels (HA x @PI, in which x represents the percentage of HA content) were obtained. The synergistic effect of inorganic filler and microporous structure of aerogel led to a great improvement of mechanical and thermal properties. Most importantly, the resultant HA x @PI aerogels could maintain their excellent physicochemical properties in several extreme environments such as ultra hot (300 °C), extreme cold (-196 °C; liquid nitrogen), water soaking (2 h, 40 °C), acid (pH 2.0; 1 h, 40 °C) and alkali (pH 12.0; 1 h, 40 °C) conditions. Based on these outstanding properties, we believe that such HA x @PI composite aerogels with low cost and high performances endowed them to be an ideal candidate to be employed in several harsh environments in addition to the conventional insulation and flame-retardant materials.

Organic–inorganic composites have exhibited unexpected new properties and have received attention by many scholars. The research on acrylamide Tin(IV) boratophosphate (ATBP) is introduced in this paper. The influence of reactant concentration, mixing ratio, pH, and other experimental parameters on the properties of the ATBP was elucidated, determining which exhibits the best ion exchange capacity (IEC) of 1.4 mequiv/g, and the physical and chemical properties of the ATBP were characterized by TGA, FTIR, XRD, SEM, and EDS. Furthermore, the elution concentration, elution performance, and thermal stability of ATBP were also studied. It was amazing to find that the distribution coefficient of ATBP was 337 mL g–1 for Fe3+. And the adsorption mechanism of ATBP was also studied from the thermodynamics, kinetics, and adsorption isotherm. The ATBP cation exchanger has a good application prospect in the removal of Fe3+ from acid polluted water.

Nowadays, the separation efficiency and stability of nanofiltration (NF) membrane are of widespread concern. Inspired by the biomineralization phenomenon and its unique structure with siliceous framework, a polyimide (PI) NF membrane decorated with “silica hard phase-polymer soft phase” 3D interwoven sponge bionic structure was fabricated via a simple and effective one-step phase inversion strategy. The obtained membranes demonstrated high pure water permeability of 65 L/(m 2 ·h) and rejections of Na 2 SO 4 (91.55%) and NaCl (30.21%) at 0.4 MPa, respectively. Moreover, siliceous sponge-like structures were determined by SEM analysis, with the degree of cross-linking after membrane pore regulated as high as 88.89%. The integrity and long-term stability of the membrane in different organic solvents, including methanol, cyclohexane, acetone, ethyl acetate, n -heptane, absolute ethanol and toluene were maintained for 72 h at 0.8 MPa. Furthermore, the PI/SiO 2 membrane with siliceous sponge biologically unique structure gives rise to a scope of bioinspired membranes and shows promising prospect for the treatment of solutions in extreme environments.
