Abstract ：
Herein, we present the synthesis and characterization of a novel phosphorus-containing epoxy co-curing agent, ANVD, fabricated via a one-pot method utilizing vanillin, 1,5-diaminonaphthalene, and DOPO as raw materials. Structural analysis conducted through FTIR and NMR spectroscopy confirmed the composition of ANVD. Differential scanning calorimetry (DSC) results indicated ANVD has significant contribution to the curing crosslinking of DGEBA, resulting in a slightly decreased Tg value for EP/ANVD compared to EP/DOPO, albeit still notably higher. Thermogravimetric analysis (TGA) revealed a reduction in the T5% and Tmax values of EP/ANVD, yet ANVD's superior char-forming ability increased char residue mass at elevated temperatures. Combustion tests showcased the outstanding flame retardancy of EP/ANVD, with EP/ANVD-5 exhibiting a limiting oxygen index (LOI) value of 33.2 % and achieving a V-0 rating in the UL-94 test. Furthermore, EP/ANVD-5 displayed a notable decrease of 38.6 % and 32.1 % in pHRR and av-HRR, respectively, compared to pure EP, surpassing EP/DOPO with equivalent phosphorus content. Analysis of decomposition products in both condensed and gas phases revealed ANVD's role in forming dense and continuous expanded char layers during combustion, releasing phosphorus radicals and non-combustible gases, thus exhibiting dual-phase flame retardant effects. Additionally, EP/ANVD-3 exhibited enhanced mechanical properties, with tensile strength and modulus increasing from 68.5 MPa and 0.75 GPa to 76.5 MPa and 0.86 GPa, respectively, compared to pure EP. Overall, the introduction of the bio-based flame retardant ANVD presents promising opportunities for the utilization of bio-based materials in flame retardancy applications.

Abstract ：
The development of dual-functional composite materials that integrate efficient electromagnetic wave (EMW) absorption and thermal conductivity is a crucial advancement in addressing the issues of electromagnetic pollution and heat accumulation in electronic devices. In this work, NixCoy-C/PAM hydrogels derived from mixed metal MOF-74 were successfully fabricated by in situ radical polymerization with the assistance of an external magnetic field. The properties of NixCoy-C/PAM were optimized by varying the ratios of cobalt and nickel metals as well as their oxides, thereby providing opportunities for the creation of advanced electromagnetic wave absorbers. When the Ni/Co ratio was increased to 1:1, Ni1Co1-C/PAM demonstrated superior EMW absorption performance at a filler ratio of 3 wt%. This configuration exhibited a minimum reflection loss of -57.8 dB at 8.64 GHz with a thickness of 3.6 mm, alongside an effective absorption bandwidth extending up to 5.81 GHz with a thickness of 2.3 mm. Furthermore, magnetic orientation within the filler facilitated enhanced heat transfer by establishing high-efficiency thermal conductive pathways. This study offers valuable insights into designing polymer composites characterized by improved thermal conductivity and robust EMW absorption capabilities.

Abstract ：
Electronic grade hydrogen peroxide plays a crucial role in the fabrication of large-scale integrated circuits. However, hydrogen peroxide prepared by the anthraquinone method contains impurities such as lead ions (Pb2+) and phosphate, which can seriously affect the yield of the circuit. Traditional adsorbent materials have difficulty in solving the problem of simultaneous adsorption of trace anions and cations in hydrogen peroxide due to the single adsorption site and poor adsorption kinetics. In this study, UiO-66-NH2 was prepared by introducing a -NH2 group on the terephthalic acid ligand, and a series of hybrid matrix hollow fiber membranes with different UiO-66-NH2 contents were prepared by loading it on polysulfone (PSF). This initiative not only improved the pore size and water flux of hollow fiber membranes but also enhanced the removal efficiency of ions from hydrogen peroxide solution, thereby facilitating practical application. Among them, UiO-66-NH2@PSF-1.5 showed the best adsorption of phosphate and lead ions with adsorption capacities of 3.099 and 2.160 mg g(-1) and reached the removal efficiency of 67.1 and 60.1%, which fully confirms the practicability in the purification of electronic chemicals. This work innovatively proposes that UiO-66-NH2@PSF hybrid matrix hollow fiber membranes have great potential as simultaneous adsorbents for cations and anions in the efficient purification of electronic grade solvents.

Abstract ：
Oil/water separation of emulsion stands as one of the most arduous and challenging aspects in oily wastewater treatment which represents a perennial trouble for humanity. Herein, positively charged hydrophobic polymer foams (PCHPFs) were fabricated by water-in-oil (W/O) high internal phase emulsion (HIPE) polymerization followed by quaternization, employing 4-vinylbenzyl chloride (VBC) and 4-tert-butylstyrene (tBS) as the comonomers. The quaternization degree of PCHPFs which can be adjusted by varying the VBC/tBS ratio has an important influence on the emulsion separation performance based on the charge demulsification mechanism. The porous morphologies of PCHPFs were revealed by SEM. The successful fabrication of PCHPFs was confirmed by FTIR and XPS. As VBC/tBS ratio increased from 0.5:1-5:1, the emulsion separation efficiency of PCHPFs first increased to a maximum of 95.9 % at 2:1 and then decreased. Additionally, the PCHPFs demonstrated robust hydrophobicity (water contact angles > 143 degrees), exceptional oil-water selectivity, remarkable oil-water separation capability, coupled with a certain absorption capacity for various oils and organic solvents (5-14 g/g). Given these advantages, PCHPFs are anticipated to emerge as an ideal solution for emulsion separation. Most importantly, the methodology for generating PCHPFs via quaternization in this research offers an innovative avenue in the design of charge demulsification materials.

Abstract ：
The improper disposal of waste high purity acetonitrile (HPA) not only causes environmental degradation but also poses significant risks to human health. One of the major challenges in the recycling and reuse of waste HPA is the removal of trace metal ions. In this study, we successfully fabricated a chitin/ZIF-67 composite hydrogel (CZ-n) by one pot in situ synthesis method for the purification and recovery of waste HPA for the first time. ZIF-67 was embedded into chitin through hydrogen bonding and coordination and provided more active adsorption sites, which resulted in CZ-3 with higher adsorption capacity than CZ-0. The maximum adsorption capacities of CZ-3 for Zn2+ and Ag+, as determined by fitting the Langmuir model, were 85.46 mg·g-1 and 91.26 mg·g-1, respectively. CZ-3 was able to effectively decrease the metal ion (Zn2+ and Ag+) concentration to below 10 ppb within 24 h through a monolayer adsorption process using chelation. Furthermore, the adsorption capacity remained satisfactory even in the presence of an equivalent concentration of NaCl, and CZ-3 exhibited remarkable reusability, with a removal rate exceeding 80 % after five cycles. Additionally, it also displayed notable biodegradability, with complete degradation observed within 60 days. These results indicated that CZ-3 could be a potential absorbent in the purification and recovery of waste HPA. © 2024 Elsevier B.V.

Abstract ：
It is a great challenge to develop thermal interface materials that enable fast heat transfer between the surface of microelectronic materials and heat sinks. In this paper, multi-walled carbon nanotube/epoxy composites (EPNH2-x) were synthesized by amidation reaction using aminated epoxy resin as matrix and carboxylated multiwalled carbon nanotubes. EP-NH2-x can reduce the interfacial thermal resistance and the promotion of phonon conduction through the chemical bonding connection between the resin and the carbon nanotubes, which will in turn improve the thermal conductivity of the composites. The thermal conductivity of EP-NH2-10 reaches 0.531 W & sdot;m- 1 & sdot;K- 1 at a and has good variable temperature cycling stability, internal elasticity and surface adhesion. This work highlights the potential application of carbon materials to improve the thermal conductivity of epoxy resins.

Abstract ：
Electronic-grade isopropyl alcohol is widely utilized in the cleaning of semiconductors and microelectronic components. Removing ions like Pb2+ is crucial since the presence of impurities may cause degradation of electronics, increased failure rates, and short circuits. Membrane materials offer a number of advantages in the field of adsorption separation; however, the lack of adsorption sites results in limited adsorption capacity. In the current work, guanidino-grafted NH2-MIL-101(Fe) was incorporated into polyvinylidene fluoride (PVDF) to prepare MOF/PVDF mixed matrix membranes (NM/PVDF) for the removal of Pb2+ from isopropanol. Benefiting from the larger specific surface area and more lone electron pairs in the guanidine group, the Pb2+ adsorption capacity of the as-prepared NM/PVDF membrane was 29.4458 mg/g, which was higher than that of the NH2-MIL-101(Fe)/PVDF membrane (20.9306 mg/g) and the pure PVDF membrane (6.7324 mg/g). The NM/PVDF membrane was able to reduce the concentration of Pb2+ from 500 to 86.73 ppb. This work highlights the potential of guanidine-grafted Fe-based MOFs/PVDF membranes as adsorbents for acquisition of electronic-grade solvents.

Abstract ：
The ring opening copolymerization (ROCOP) of epoxides and cyclic anhydrides is one of the most important ways to synthesize polyesters both in industrial and academic fields. Herein, the zeolitic imidazolate framework-67 (ZIF-67) was used as a heterogeneous catalyst for the ROCOP of epoxides and cyclic anhydrides without co-catalyst and initiator. Notably, the obtained polyesters with alternate structures were proved by the 1H NMR spectrum and FTIR spectrum, which indicate the ROCOP is alternatively copolymerized. Kinetic study of the ROCOP of cyclohexene oxide (CHO) and phthalic anhydride (PA) shows that the polymerization reaction is first-order kinetics. The apparent activation energy (Ea) of the ROCOP of CHO and PA catalyzed by ZIF-67 was found to be about 104.4 KJ/mol. A possible mechanism of ROCOP of CHO and PA is that the metal Co coordinates with the oxygen atom on the monomer to weaken the C-O bond thereby opening the ring structure and initiating the copolymerization reaction. In this study, a new system for the copolymerization of epoxide and anhydride catalyzed by heterogeneous catalysts was discovered, which has important guiding significance. The zeolitic imidazolate framework-67 was used as a heterogeneous catalyst for the alternatively ring opening copolymerization of epoxides and cyclic anhydrides without co-catalyst and initiator. image
