Nevertheless, design methodologies that rely on extensive experimental experience have limited the applicability of conductive aerogels in radar-infrared compatible stealth applications. In this study, finite element simulations of microwave absorption and heat transfer properties are conducted using a simplified two-dimensional model. The wave-absorbing and heat-insulating properties of graphene aerogel as influenced by the pore structure are accurately predicted. The preparation of foamed graphene aerogels with isolated pores was conducted using a surfactant foaming process, with the process guided by simulation predictions. The size, number, and spacing of the bubbles can be flexibly controlled to provide the aerogel with an appropriate density and porosity, which balances the contradiction between the high attenuation capability and the impedance-matching nature. This enables the foamed aerogel to achieve reflection loss of −75.5 dB and ultra-wide effective absorption bandwidth of 9.5 GHz. Furthermore, the low density and isolated pores bestow upon the aerogel material exemplary thermal insulation capabilities, which masked the radiant temperature of a hot object from 135 °C to 50.8 °C.

Despite their importance, related investigations are frequently overlooked, especially in the case of magnetorheological elastomers (MREs). In this study, the processing-induced changes were investigated within an isotropic MRE based on a thermoplastic elastomer (TPE) matrix loaded with carbonyl iron (CI) microparticles. Systematic thermomechanical tests in the molten state were used to mimic the processing conditions, revealing the time evolution of the particle/matrix interactions. The interactions manifested as an increase in the viscoelastic properties, which was attributed to the development of a secondary network composed of the confined polymer chains in the vicinity of the CI particles. The restricted mobility improved the reinforcing effect and structural integrity but diminished the field-induced stiffening of the composite, i.e., the magnetorheological effect. The existence of the particle/matrix covalent bonding was postulated and explained based on the coupling reaction between the thermomechanically-induced radicals formed in the polymer chain and the alkoxyl radicals on the surface of the CI particles. The new findings are highly relevant for the further development of reprocessable and recyclable TPE-based MREs, while the robust measuring protocol is deemed to be implementable for studying particle/matrix interactions in diverse composite systems.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"298 ","pages":"Article 112399"},"PeriodicalIF":12.7,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dipole polarization, interfacial polarization, and magnetic coupling strength were enhanced to realize dielectric-magnetic synergies coupled with Ti₃C₂T_x MXene for exceptional EMA performance.

Additionally, a bionic periodic structure inspired by the sea urchin shell was designed based on the high-performance absorber FC3/MXene, achieving the impressive value of −64.48 dB and a whole absorption band covering 2−18 GHz, thanks to its isotropic structure and high porosity. Furthermore, in radar cross-section (RCS) simulations, FC3/MXene absorbers effectively reduce the radar detection distance of an unmanned aerial vehicle (UAV), demonstrating excellent stealth characteristics.

The water desorption process of the SAP-n/RHA composite within cement pastes was characterized using ¹H NMR, isothermal calorimetry, and internal relative humidity.

The forming quality, wear performance, and biofunctionality of LMDed 3ZrO₂/Ti–3Cu samples were characterized through specific electron microscopy, mechanical wear tests, and <em>in vitro</em> cell tests. A slightly lower energy density resulted in the best fabrication quality. The spherical morphology of the powders compensated for the different thermodynamic properties of nano-ZrO₂, achieving higher densification.

In this study, a novel method was proposed for preparing flame-retardant cellulose nanofiber laminates, focusing on raw material selection, modification method, and laminated structure. The silica in natural straw was retained, and the fibers were swollen using the green and environmentally friendly deep eutectic solvent, resulting in the partial dissolution of cellulose. This process reduced the energy consumption of mechanical treatment during the preparation of straw cellulose nanofibers. Sulfonic acid groups were grafted onto the straw cellulose to impart flame-retardant properties to the material. By leveraging the laminated structure to block heat transfer between layers, the material achieved excellent flame-retardant performance and mechanical properties. The flame-retardant straw cellulose nanofiber laminate achieved an LOI of 61.9 %.

This strategy is based on a rigid neural network (CNF) framework and SPI-based dynamic network system. Functionalized nanofibers (CNF@TP) were tightly connected to SPI through Schiff base reaction and strong hydrogen bonding. The dry and wet shear strength of plywood prepared with modified adhesive reached 1.89 MPa and 1.25 MPa respectively, which were 117.2 % and 119.3 % higher than SPI adhesive. The inorganic mineral component (ZnO) formed an organic-inorganic hybrid structure with soy protein, which improved the mildew resistance, flame retardancy and UV resistance of the adhesive.
