Silk fibroin (SF)-based sensor devices are promising candidates due to their biocompatibility, biodegradability and low manufacturing cost. However, the existing SF-based sensor devices are difficult to achieve the excellent mechanical properties, high conductivity and anti-liquid-interfering properties. Aramid nanofibers (ANFs) with a high aspect ratio and excellent mechanical properties are usually served as the stiff segments to fabricate high-performance composites. Nevertheless, ANFs dispersion prepared via deprotonation exhibit high sensitivity to water, along with long preparation time (one week), limiting its practical applicability. Herein, inspired by the extraordinary mechanical properties of natural soft tissues, the silk fibroin/aramid nanofibers (SF/ANFs) composites were fabricated by the biomimetic hybridization between the SF and water-dispersible ANFs. The SF/ANFs composites showed higher mechanical properties than that of other previously reported SF-based composites, which were further modified with gold nanoparticles (Au NPs) and fluorocarbon (FC) resin to facilitate the integration of conductivity and hydrophobicity. As a result, the flexible and conductive SF/ANFs/Au@FC composite as piezoresistive sensor exhibited excellent sensitivity, broad pressure detection interval and anti-liquid interfering properties. This work presented a simple and time-saving procedure to prepare the water-dispersible ANFs, opening up new possibilities for hybridization with water-soluble materials. The mechanistic insights and manufacturability provided by the composite and sensor might present further opportunities for materials design and technological innovation.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"268 ","pages":"Article 111206"},"PeriodicalIF":8.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917384","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}

Although recent works successfully constructed anisotropic thermal networks in the polymer-based composites, the connectivity of the ceramic grains was inferior, leading to the high contact thermal resistance (<em>R</em>_cf) and less constraint of the thermal expansion of polymer matrices.

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. Consequently, the multi-level structure-activity relationship between polymer molecular structure, nanofiber morphology, interlaminar topology, and composite macroscopic properties was established to pave the way for precise atomic-level construction of interlaminar structures in laminates.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"267 ","pages":"Article 111205"},"PeriodicalIF":8.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860245","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}

Through a systematic analysis of morphological changes and filler network formation, we reveal how boron nitride, as a secondary nanofiller, mitigates the NTC effect by reducing electrical contact points between graphene nanoplatelets and increasing viscosity to prevent filler re-agglomeration. The volume ratio between polymer matrix and conductive filler has been identified as a key factor in eliminating the NTC effect in CPCs with 2D fillers.

The embedded SiC particles induce a pinning effect that facilitates load transfer among fibers, and suppresses crack propagation, and enhances the joint's lap shear strength. Through comprehensive evaluations, including lap shear tests, morphological analysis of fractures and welding seams, and temperature monitoring at the welding interface, the fracture modes and heat generation mechanisms of SiC particle-reinforced ultrasonic welded CFRTP joints are systematically investigated and clarified.
