To address this issue, a new type of nanoconfined polymer brush (PB) with amide functional groups is designed and employed for improved antifouling properties and enhanced water evaporation. The PB utilizes graphene oxide nanosheets of atomic thickness as the substrate, with polymers growing on the nanosheets as bristles. The hydrophilic amide groups and nano-space confinement of PBs create layers with strong Donnan effect that trap five-fold more intermediate water (IW) than bulk water. Consequently, the high contents of IW act as an effective water evaporation source within the nanoconfined channels, preventing salt crystallization and enhancing water evaporation (2.25 kg m<sup>−2</sup> h<sup>−1</sup>) with a light-to-heat conversion efficiency of about 86.9%.

The rheological properties of different STF systems and their effects on the stab resistance of composites were studied, and the effects of doped nanowire MWCNT and ANF on the shear-thickening performance and stab resistance were compared. The results show that the STF doped with nanowires can significantly enhance the stab resistance.

Here, we focus on the adhesion of a natural rubber matrix to a single metal wire, characterized using the Rubber Cord Adhesion Inflation Test. This protocol allows for the observation of a stable steady-state crack propagation under an axisymmetric configuration. An experimental protocol is proposed that utilizes a pre-load sequence to achieve a controlled softening of the rubber sheath surrounding the wire. Quantification is carried out through numerical simulations and subsequent material characterization. The adhesion results indicate that the pre-loading sequence reduces the specimen’s overall resistance to decohesion. A more detailed analysis reveals that the critical SERR value is also lower.

This study enhances the performance of a TENG device by incorporating silver nanowires (AgNWs) into ionic liquid-mixed polyvinylidene fluoride (PVDF) through an additive manufacturing process. The dielectric properties and output performance of TENGs are analysed by varying AgNWs concentrations in ionic liquid-mixed PVDF, serving as the negative tribolayer, while polyamide 6 (PA 6) functions as the positive tribolayer. Results indicate that the optimal addition of 7 % AgNWs achieves a maximum open-circuit voltage of 380 V, a short-circuit current of 25.5 μA, and a power density of 9.5 W/m<sup>2</sup>. Moreover, the addition of an ionic liquid to PVDF enhanced the development of a well-aligned electroactive β-phase and functioned as a conductive pathway, capturing charges from the surface and transferring them into the bulk material. The presence of AgNWs creates charge-trapping sites by acting as a microcapacitor, increasing charge density. Additionally, the additive manufacturing process improves surface roughness and ensures uniform layer deposition, enhancing contact between tribolayer and improving charge transfer efficiency. The findings show that optimizing AgNWs composition and surface microstructure enhances TENG performance, offering promising applications in energy harvesting and self-powered technologies.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"303 ","pages":"Article 112604"},"PeriodicalIF":12.7,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143913197","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}
