Abstract ：
首先，将9,9-二(3,5-二甲基-4-羟基苯基)芴（DMBHF）、9,9-双(4-羟苯基)芴（BHF）和4,4'-二氟二苯甲酮（DFB）在高温下缩聚，得到聚芴醚酮（PFEK-x)(x=30、40、50,x为DMBHF含量，以DFB的物质的量计，下同）；接着，利用溴代反应将PFEK-x的甲基功能化为溴甲基；然后，通过4-羟基苯磺酸钠的S_N2亲核取代制得具有不同离子交换容量的磺化聚芴醚酮（SPFEK-x）；最后，通过溶液浇铸法成膜并酸化，制得新型低成本质子交换膜（PEMs）。采用~1HNMR、FTIR、TGA对其进行了表征，并对其性能进行了测试。结果表明，SPFEK-40膜具有较高的质子传导率及离子选择性、较低的钒离子渗透率及面电阻，综合性能优异。以SPFEK-40膜组装的全钒液流电池（VRFB）在电流密度为80 m A/cm~2时的能量效率为88.2%，高于以Nafion 212膜组装的VRFB的84.8%。此外，以SPFEK-40膜组装的VRFB在30次循环后放电容量保持率为84.3%，远高于以Nafion 212膜组装的VRFB(66.1%）。该合成路线的原料来源广泛，价格低廉，不涉及危险的磺化反应，易于工业放大。制得的SPFEK-x均具有良好的机械性能和氧化稳定性。

Abstract ：
Poly(fluorenyl ether ketone)s (PFEK-x) were firstly synthesized from high-temperature polycondensation of 9,9-bis(3,5-dimethyl-4-hydroxyphenyl)fluorene (DMBHF), 9,9-bis(4-hydroxyphenyl) fluorene (BHF) and 4,4'-difluorophenone (DFB), herein, x=30, 40, 50, and refers to the content of DMBHF (based on the amount of substance of DFB, the same below). The PFEK-x obtained were then brominated by bromination of the methyl groups and then reacted with sodium 4-hydroxybenzenesulfonate to yield sulfonated poly(fluorenyl ether ketone)s (SPFEK-x) with different ion exchange capacities. Finally, novel and low-cost proton exchange membranes (PEMs) were prepared by solution-casting SPFEK-x into membranes and acidification. The samples were characterized by 1HNMR, FTIR and TGA, followed by analysis on their properties. The results showed that SPFEK-40 membrane exhibited excellent comprehensive performances, such as high proton conductivity and icon selectivity, low VO2+ permeability, and low surface resistance. The energy efficiency of vanadium redox flow battery (VRFB) assembled with SPFEK-40 membrane reached 88.2% at a current density of 80 mA/cm2, higher than that of the VRFB assembled with Nafion 212 (84.8%). In addition, the discharge capacity retention ratio of the VRFB assembled with SPFEK-40 membrane after 30 cycles was 84.3%, which was much higher than that of the VRFB assembled with Nafion 212 (66.1%). Moreover, the synthetic route could be scaled-up easily since it was based on inexpensive raw materials without dangerous sulfonation reactions. The SPFEK-x membranes also displayed good mechanical properties and oxidation stability. © 2024 Fine Chemicals. All rights reserved.

Abstract ：
As core components in electric/electronic fields, dielectric materials have recently received ever-increasing interests. Among them, polymer-based dielectric composites have drawn ever-increasing attentions due to their high-temperature resistance and excellent processibility. However, state-of-art studies mostly focus on the modification of single-phase filler, while the heterogeneous three phase interactions between fillers and polymer matrix are rarely studied. To fill this gap, in this study, a novel strategy of interfacial design and structural construction of three-phase BaTiO3/rGO/polymer nanocomposites have been promoted to simultaneously build interfacial barriers between adjacent rGO nanosheets and to enhance the interfacial polarization of rGO nanosheets for improved dielectric, thermal and mechanical properties. The dielectric constant of 0.6 wt% BT/ARGO/PEI reached 644@1 kHz with a dielectric loss of only 0.218, while these values for 0.5 wt% ARGO/PEI composites are 471 and 0.489, respectively. Meanwhile, the breakdown strength almost doubled (from 48 kVmm(-1) to 87 kVmm(-1)) upon the addition of BaTiO3 (BT) nanoparticles. Moreover, the introduced BT nanoparticles significantly enhanced the intermolecular frictions between different materials and contributed largely to promoted mechanical and thermal properties. We therefore speculate this work establishes a strong foundation for fabricating three heterogeneous-phase high dielectric polymer materials with excellent dielectric, thermal and mechanical properties. Highlights center dot Graphene oxide was modified by APTES and reduced by L-Ascorbic Acid. center dot Three-phase BT/ARGO/PEI composites showed enhanced dielectric properties. center dot The incorporated BT nanoparticles reduced the dielectric loss. center dot The thermal and mechanical properties of BT/ARGO/PEI composites are optimized. center dot Interfacial interactions between different phase of materials are studied.

Abstract ：
The effective solution to current energy and environmental issues lies in the advancement of renewable energy conversion and storage technologies. In this work, an ultra-thin-walled hierarchical porous carbon (UHPC) with fluffy three-dimensional (3D) interconnected network structure was synthesized by pyrolysis of petroleum residue and aluminum isopropoxide. Then, a nitrogen-sulfur co-doped UHPC (NS-UHPC) was prepared and employed as a sulfur-loading host to achieve NS-UHPC@S composite after sulfur impregnation. After that, the electrochemical performances are explored utilizing the NS-UHPC@S composite as electrode active material for lithium-sulfur battery (LSB). The as-prepared NS-UHPC possesses a specific surface area of 1031.32 m2 g-1 and a pore volume of 0.82 cm3 g-1 with abundant active sites for absorption of polysulfides. Meanwhile, it maintains a fluffy 3D interconnected network structure with graphene-like sheets on its surface. The sulfur loading of the NSUHPC reaches as high as 79.58 wt% after sulfur impregnation. In addition, the resulting NS-UHPC@S composite exhibits an initial specific capacity of 1255.17 mAh g-1 at 0.1C, and after 700 cycles, the capacity decay rate per cycle is 0.0323 %, demonstrating its excellent cycling stability. Therefore, the NS-UHPC is a desirable sulfurloading host for high-performance LSB.

Abstract ：
Developing effective adsorbents for wastewater purification is crucial, as excessive emissions of toxic dyes and heavy metal ions have been proven harmful to ecosystems and human health. A NiFe-layered double hydroxide/graphitic porous carbon (NiFe-LDH/GPC) composite was fabricated by introducing NiFe-LDH nanosheets into GPC via a simple hydrothermal method to utilize the advantages of both materials fully, and thus ultimately obtain a composite adsorbent with improved adsorption properties. The samples obtained were comprehensively characterized by various characterization means, and the effects of several critical influential factors on the pollutant uptake capability of the NiFe-LDH/GPC were also studied through batch experiments. The results show that the as-synthesized NiFe-LDH/GPC exhibits a three-dimensional (3D) fluffy ultrathin-wall hierarchical porous structure, which possesses a high specific surface area and pore volume separately up to 506.74 m2/g and 0.22 cm3 g−1 as well as a relatively narrow pore size distribution. These characteristics bring advantages to enhance the adsorption ability of the NiFe-LDH/GPC for cationic/anionic dyes and heavy metal ions such as congo red (CR), malachite green (MG) and hexavalent chrome (Cr(VI), which reached the maximum adsorption capacity of 1726.51 mg/g, 1157.11 mg/g and 155.72 mg/g under the optimum conditions, respectively. Meanwhile, the adsorption behavior can be well described by the pseudo-second-order kinetic model and Langmuir isotherm model, reflecting that the sorption process mainly occurred chemically in the adsorbent monolayer. Furthermore, the NiFe-LDH/GPC maintained relatively high adsorption performance after multicycle testing, manifesting its good recyclability and stability. © 2024 Elsevier B.V.

Abstract ：
Creating petroleum residue-based new functional materials are vital for the sustainable development of petroleum residues. This study developed a method to prepare a petroleum residue-based ultrathin-wall graphitized mesoporous carbon (PGMC) with high specific surface area by the carbonization of a composite of the petroleum residue uniformly mixed with aluminium isopropoxide. Results show that the PGMC possesses a highly fluffy ultrathin-wall mesoporous structure with a high degree of graphitization. It had a high specific surface area of 1174 m2 g−1 with a high pore volume of 4.57 cm3 g−1 and a narrow pore size distribution at 8.09 nm. These unique features endow the PGMC with excellent adsorption properties for Congo red, Malachite green, and Methylene blue removal. The experimental data were better described with Freundlich isotherm and Quasi-second-order kinetic models. Thermodynamic analysis indicated a spontaneous and endothermic adsorption process. The adsorption mechanisms proposed that pore-filling effect, π-π conjugation, and electrostatic interaction were the main interactions between the PGMC and dyestuff, followed by functional groups and hydrogen bonding. Moreover, the PGMC could maintain good adsorption rates after five cycles, proving that it is an effective adsorbent with good adsorption ability and cycling stability. © 2024 Elsevier B.V.

Abstract ：
A three-dimensional continuous network graphite nanosheets-based carbon foam (CF) was developed by vacuum carbonization of nano-Al2O3/epoxy composites, and employed as support to achieve a shape-stabilized stearic acid (SA)/CF composite phase change material. The influence of preparation temperature of CF on the thermal storage performances of the SA/CF composites was investigated. Results indicate that the nano-Al2O3 can effectively improve the graphitization degree of resulting CF and its compatibility with SA by promoting the growth of graphite nanosheets. The thermal conductivity of SA/CF composite increases with the increasing carbonization temperature of CF. When the carbonization temperature is 1700 degrees C, the resulting CF (CF-1700) is found as a desirable support for SA. The as-prepared SA/CF-1700 composite has a high thermal conductivity of 3.15 W/mK increasing by nearly 1270 % that of SA, and meanwhile presents a greatly enhanced compressive strength of 6.97 MPa by about 2.13-folds compared with the CF-1700. In addition, the composite with good interfacial bonding exhibits excellent leakage-prevention performance with a high SA loading amount of 77.81 % during the phase change process. In addition, its melting and crystallization enthalpies arrive at 176.6 and 179.7 J/g with an enthalpy efficiency of 82.67 %, respectively. More importantly, the composite displays remarkable chemical stability and thermal storage durability after 200 thermal cycles, revealing great potential in heat storage applications.
