Abstract ：
In order to overcome the performance barriers of polylactic acid (PLA), a multifunctional layered chitosan derivative, DAMC-Al, is synthesised and used as an intumescent flame retardant. The acid sources used in this work are 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide and amino trimethylene phosphonic acid, which act synergistically to facilitate the conversion of chitosan to carbon. The combustion tests demonstrate that the PLA/ 5DAMC-Al exhibits excellent flame-retardancy with a limiting oxygen index of 30.3 % and a UL-94 flammability rating of V-0. The heat release rate and total heat release are significantly reduced compared to pure PLA, and the residual carbon expands rapidly. In addition, the composite has improved toughness while maintaining the stiffness of the PLA substrate, with a 31.0 % increase in elongation at break. DAMC-Al can also effectively block the transmission of 95 % of ultraviolet lights, protecting the PLA macromolecular chain from high-energy ultraviolet damage. Actually, the ultraviolet protection factor of PLA/5DAMC-Al is determined to be as high as 51.43. Furthermore, the soil degradation tests show that PLA/5DAMC-Al has the same excellent natural degradation properties as PLA.

Abstract ：
In recent years, thermoplastic polyurethane elastomer has shown great application prospects in the fields of polymer film due to its outstanding tensile properties, high elasticity, wear resistance, oil resistance, low temperature resistance, wide range of hardness, and other properties. However, its flammable properties greatly limit its application in the field of polymer film. The self-made GO was used as a carbon source, phenylboronic acid as an acid source, ammonium polyphosphate (APP) as an acid and gas source, and intumescent flame retardant (IFR) was compounded. The IFR was introduced into thermoplastic polyurethane (TPU) to prepare a series of IFR/TPU composite films with different formulations. The results show that PA and GO can make up for the loss of mechanical properties caused by the addition of APP and improve the thermal stability of the composite film, and the IFR flame retardant composed of the two and APP can effectively improve the flame retardancy of the composite film. When the additions of APP, PA, and GO were 10, 3, and 0.75%, respectively, the LOI value of the IFR/TPU composite material reached 29.5, the flame-retardant grade reached V-0, and its peak heat release rate, total heat release, peak smoke production rate, and total smoke release were 86.0, 64.9, 70.5, and 21.7%, greatly lower than pure TPU, respectively. The flame retardancy of the spacer composite membrane constructed from Ti-7 was significantly improved, and the burn-through time of the single-layer film sample was increased by 2.22 times, and the double-layer film sample was increased by 2.63 times.

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 ：
Proton exchange membranes (PEMs) are an important type of vanadium redox flow battery (VRFB) separator that play the key role of separating positive and negative electrolytes while transporting protons. In order to lower the vanadium ion permeability and improve the proton selectivity of PEMs for enhancing the Coulombic efficiency of VRFBs, herein, various amounts of nano-sized SiO2 particles were introduced into a previously optimized sulfonated poly(arylene ether) (SPAE) PEMs through the acid-catalyzed sol-gel reaction of tetraethyl orthosilicate (TEOS). The successful incorporation of SiO2 was confirmed by FT-IR spectra. The scanning electron microscopy (SEM) images revealed that the SiO2 particles were well distributed in the SPAE membrane. The ion exchange capacity, water uptake, and swelling ratio of the PEMs were decreased with the increasing amount of SiO2, while the mechanical properties and thermal stability were improved significantly. The proton conductivity was reduced gradually from 93.4 to 76.9 mS cm(-1) at room temperature as the loading amount of SiO2 was increased from 0 to 16 wt.%; however, the VO2+ permeability was decreased dramatically after the incorporation of SiO2 and reached a minimum value of 2.57 x 10(-12) m(2) s(-1) at 12 wt.% of SiO2. As a result, the H+/VO2+ selectivity achieved a maximum value of 51.82 S min cm(-3) for the composite PEM containing 12 wt.% of SiO2. This study demonstrates that the properties of PEMs can be largely tuned by the introduction of SiO2 with low cost for VRFB applications.
