Abstract ：
Polymer matrix composites with excellent thermal management performance have emerged as remarkable materials in the realms of microelectronic devices and wireless communication technologies. However, achieving high thermal conductivity in most composites often requires a high filling load, which will compromise other desirable properties. Herein, utilizing physical foaming and vacuum infiltration methods, we introduce a 3D honeycomb composite consisting of surface-hydroxylated hexagonal boron nitride (OH-BN) and epoxy. The 3D OH-BN honeycomb foam in the composite features a lightweight design (0.33 g/cm3), high strength (7178 times its own weight) and prominent heat transfer performance. Significantly, these composites achieve notable thermal properties, including high through-plane thermal conductivity (2.073 W m−1 K−1) and relatively low thermal resistance (0.995 °C/W) at a reduced filling load (17.2 vol%). In comparison with pure epoxy, the through-plane thermal conductivity is enhanced by an impressive 894 %, while the thermal resistance is reduced to 1/9.4 of that observed in pure epoxy. Besides, the 3D honeycomb composites combine outstanding mechanical performance, low dielectric properties and excellent insulation, underscoring their potential in the field of thermal management applications in microelectronic devices, wireless communication systems and integrated circuits. © 2024

Abstract ：
以异佛尔酮二异氰酸酯(IPDI)为聚己二酸-对苯二甲酸丁二酯/聚乳酸(PBAT/PLA)共混物的增容剂，通过熔融共混法制备了PBAT/PLA/IPDI共混粒子并吹制得到薄膜。采用红外光谱、扫描电镜、差示扫描量热分析、拉伸试验、热重分析和水蒸气透过率测试等研究了不同含量IPDI对共混薄膜形态结构、结晶性能、力学性能、热性能和阻隔性能的影响。结果表明，IPDI的异氰酸酯基团能与PBAT和PLA发生化学反应，分散相尺寸变小，两相界面变得模糊，有效改善了共混物的相容性。随着IPDI含量的增加，共混物中PBAT的结晶度升高，薄膜的拉伸强度逐渐增大，水蒸气阻隔性能呈现先增大后减小的趋势。当IPDI质量分数为0.5%时，PBAT/PLA/IPDI薄膜的横纵向拉伸强度相较于纯PBAT/PLA薄膜分别提升了74.2%和28.6%，断裂伸长率维持在790%和244%，水蒸气透过率降低了38.2%，表现出良好的力学和水蒸气阻隔等综合性能。

Abstract ：
Isophorone diisocyanate (IPDI) as reactive compatibilizer was introduced into poly(butylene adipate terephthalate) (PBAT)/polylactic acid (PLA) blend by melt blending and extruded into blown films. The effect of IPDI content on the phase morphology, crystallization behavior, mechanical, thermal and barrier properties of PBAT/PLA/ IPDI blended films were investigated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), differential scanning calorimeter (DSC), universal tensile testing machine, thermogravimetric analyzer (TGA) and water permeability tester. Results demonstrate that the —NCO groups of IPDI can chemically react with PBAT and PLA to form copolymer, which reduces the particle size of PLA dispersed phase and leads to indistinct interface between the two-phase, effectively improving the interfacial compatibility between PBAT and PLA matrix. With increasing the IPDI content in PBAT/PLA/IPDI films, the crystallization ability of PBAT matrix and tensile strength increase, whilst the water vapor barrier performance increases first and then decreases. When the mass fraction of IPDI is 0.5%, compared with the pristine PBAT/PLA film, the PBAT/PLA/IPDI packaging film shows 74.2% and 28.6% enhancement in tensile strength on the transverse direction and machine direction, respectively, maintains decent breaking elongation of 790% and 244%, meanwhile, 38.2% reduction in water vapor permeability coefficient, which suggests the balanced overall mechanical and water vapor barrier properties. © 2023 Chengdu University of Science and Technology.

Abstract ：
Photocatalysis is a promising technology for removing micropollutants in water. However, developing efficient and stable catalysts remains a challenge. In this work, a novel step-scheme (S-scheme) heterojunction of WO3/SnIn4S8 (WSI) was constructed through the combined process of in situ precipitation with hydrothermal synthesis to simultaneously realize photocatalytic degradation of bisphenol A(BPA) and reduction of Cr(VI) in contaminated water. Results showed that the WSI S-scheme heterojuction has a synergistic effect for the removal of BPA and Cr(VI). An optimum case of the WSI-12% heterojunction exhibited the highest photocatalytic efficiency in the degradation of BPA under visible light, which is ca. 2.5 and 3.8 times more than the pure WO(3 )and SIS, respectively. The enhanced photocatalytic activity is attributed to the formation of the WSI S-scheme heterojunctions which facilitate the spatial separation of charge carriers and preserve strong photoredox ability. Further, the S-scheme mechanism of enhanced photocatalysis was examined by the radical-trapping experiment and ESR, and superoxide and hydroxyl radicals were determined to be the major reactive oxygen species responsible for BPA degradation and Cr(VI) reduction by WSI. This work provides a novel strategy for tailoring high-performance S-scheme heterojunctions and shows the promising application in purifying wastewater with complex pollutants.

Abstract ：
It is critical to design and synthesize superior metal-free PMS catalysts, particularly to optimize the interaction between non-metallic heteroatoms and biochar, facilitating electron conduction and the generation of reactive oxygen species. Hence, this work presented a feasible synthetic strategy for anchoring phosphorus on in-situ nitrogen-doped biochar via ball milling at room temperature. Mechanical forces triggered the dehydration reaction between phosphoric acid and C-OH bonds, forming C-O-P bonds. In particular, the obtained N and P codoped biochar (NPB) showed excellent catalytic activity. The reaction and removal rate of diclofenac sodium (DS) in the NPB/PMS system were 0.3974 min(-1) and 90.08 % (only 10 min), respectively, significantly higher than those in the in-situ nitrogen-doped biochar/PMS system. The impressive catalytic efficiency was attributed to the coupling effect of high-efficiency adsorption and exceptional electron transfer capabilities. Anchoring P into the carbon structure effectively expedited the electron transfer from adsorbed DS molecules to metastable PMS complexes via the carbon-bridge effect, ultimately leading to DS degradation. The C=O groups, pyridinic N, graphitic N, and defect sites were possible active sites for PMS activation. GC/MS identified the potential degradation paths of DS, but the toxicity of DS and its intermediates was noteworthy. Furthermore, the DS degradation efficiency of the NPB/PMS system was little hampered by pH (2.95-9.07), anions, humic acid, and actual water, suggesting its application potential in real-world wastewater. Overall, this study paves a new way for constructing effective N and P co-doped non-metallic PMS catalysts, which may be expanded to other carbon materials to fulfil the unique demands of various applications.
