However, establishing direct correlations between macroscopic rheological properties and microscopic structures has proven challenging. Here, using micron sized platelet boron nitride (BN) and spherical aluminum oxide (Al₂O₃) as model fillers, we elucidate the relationship between the microscopic network structure and the macroscopic rheological properties of polydimethylsiloxane (PDMS) based composite fluids by analyzing the particle networks in conjunction with scaling theory. We find that the rheology properties of the Al₂O₃/PDMS composite fluids are different from those of the BN/PDMS composite fluids, where the Al₂O₃/PDMS composite fluids increase hyper exponentially with filling volume fraction, but the BN/PDMS composite fluids increases exponentially. The thixotropic properties reveal that the spherical Al₂O₃ particles have high recovery rate, but the platelet BN contributes to a low recovery rate. The difference in rheological performance between BN and Al₂O₃ stems from the interparticle forces and particle networks: BN particles surprisingly form colloidal-style clusters and particle networks, whereas Al₂O₃ particles create a volume-repulsion-dominated jamming structure. Using these two composite fluids as thermal interface materials, we demonstrate that the BN/PDMS composite fluids capable with better dispensing operation performance and better ability of heat dissipation for chip than the Al₂O₃/PDMS composite fluids.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"267 ","pages":"Article 111193"},"PeriodicalIF":8.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892164","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}

Herein, a Bi-modified W₁₈O₄₉/MWCNTs/PAN hybrid nanofiber membrane is successfully prepared by electrospinning and post-treatment. Relying on the synergistic effect of Bi, W₁₈O₄₉, MWCNTs, and porous structures, excellent broadband radiation protection capability is achieved: (i) Low near-infrared-visible-light (NIR-VIS) transmittance (0.62 %); (ii) Ultraviolet (UV) transmittance of only 0.012 % and UPF value as high as 2000; (iii) Mass attenuation coefficient up to 16.18 cm² g⁻¹ and attenuation ratio of 85.74 % (thickness: 4 mm) at 33 keV X-ray energy.

This paper presents in-situ measurements of process parameters related to residual stress formation, including temperature gradients, printing force fields, and deformation of printed samples. As temperature is a key factor contributing to residual stresses, this study introduces an in-situ micro-scale characterization method for the printing temperature field using temperature-sensitive prepreg filaments. The method enables accurate measurement of the full life cycle temperature data across different microscopic regions of the prepreg filament during printing. Using the measured data, including temperature, printing pressure, and tension force, this paper proposes a multi-scale process modeling method referred to as the “extrusion process-printing process combination”. This model simulates the temperature field distribution during the extrusion process, as well as the residual stress and deformation during the printing process. Simulation results were validated by experiments, with an error margin of less than 5 %. Using this model, the preliminary process optimization for reducing the residual stress was carried out. In addition, the effects of various process parameters on the temperature gradient during printing and the deformation of printed samples were analyzed.

The molecular structure of nanofibers is a crucial factor influencing their toughening performance, but the underlying <em>trans</em>-dimension structure-activity relationship remain unclear. Here, two types of polyamide-based nanofibrous veils (NF1 and NF2), characterized by distinct molecular structures, were integrated into carbon fiber/epoxy laminates to assess differences in interlaminar fracture toughness. Mode I and Mode II loading tests demonstrated significant yet distinct improvements in interlaminar fracture toughness for the two nanomodified CFRPs, attributed to intrinsic and extrinsic toughening mechanisms. NF1-modified composites exhibited superior toughening properties than NF2-modified composites, with a 186 % enhancement in <em>G</em>_<em>IC</em> and a 134 % enhancement in <em>G</em>_<em>IIC</em>. This superiority can be attributed to NF1's higher crystallinity, smaller diameter, stronger tensile strength, and greater interaction energy with epoxy resin, all of which are closely related to the molecular structure of the nanofibers. Molecular dynamics (MD) simulations provided theoretical insights into how the molecular structure of nanofibers influences interlaminar toughness. Furthermore, the original laminate static flexural properties, dynamic stiffness, and glass-transition temperature (<em>T</em>_g) are all maintained for NF1-modified composites, suggesting that enhancing interlaminar toughness can compensate for potential declines in mechanical and thermomechanical properties.
