Abstract Advances in research electronic textiles (E‐textiles) that primarily cater to wearable sensing technology have found amalgamation with self‐powered technology, especially triboelectric nanogenerators (TENGs). However, developing E‐textiles properties involves a multi‐step process and complex device structure, which is unsuitable for actual wearables. Also, the cellulose‐based fabrics highest wearability are TENG fabrication, limiting usage synthetic fabrics. Apart from wearability, self‐healing behavior another significant property recently being looked upon sensors, providing long‐term functionality. Herein, simple yet effective approach proposed develop dielectrically optimized coatings cellulose fabric‐based sensors by leveraging elastomers tunable dielectric other properties, otherwise catering domain of skin separately. The record high output performance power density 4.69 W m −2 accomplished using single fabric layer thickness 0.56 mm supports elastomeric next‐generation strategic utilization dynamic covalent chemistry imparted coating. This report provides single‐step dip coating method self‐healable E‐textile.

Bio-based epoxy vitrimers are gaining attention as sustainable alternatives to traditional epoxies due renewable starting materials and recyclability, enabling material circularity. Transesterification, a dynamic bond reaction mechanism in vitrimers, relies on ample hydroxy esters groups the polymer network rearrange under moderate conditions. To reduce reliance petroleum we investigated starch, natural feedstock rich groups. Ester densities were adjusted with an ester containing crosslinker (pentaerythritol tetrakis(3-mercaptopropionate) (PETMP)) at various molar ratios (1:0.7, 1:1, 1:1.25 1:1.5) TEMPO catalyst. The reformation efficiency of vitrimer increased 239 % from 31 when ratio changed 1:1 1:1.5. Essential behavioral parameters (dynamic exchange activation energy (Ea(d)), Arrhenius prefactor (τ0), freezing transition temperature (Tv)) analysed. Adding excess amount decreased Tg, crosslink density, Ea(d) Tv starch-based vitrimer. Adhesion tests birch veneer found that 1:1.5 had highest adhesion performance 3.02 ±0.7 MPa recovery high 91 averaging 61 +/- 23 %. These insights into density bonds active functional will contribute developing new bio-based designed

Thermoelectric textiles have garnered significant attention in energy harvesting and temperature sensing due to their comfort reliable long-term power generation capabilities. However, existing thermoelectric rarely realize antibacterial, high output performance, capabilities simultaneously. Here, we present a facile scalable method for fabricating n-type silver selenide (Ag2Se) cotton threads with exceptional output, advanced The Ag-Ag2Se segmented structures are prepared using the selenization method. Subsequently, textile consisting of 50 pairs p-n legs is fabricated, which can generate density 500 μW m-2 at difference 30 K, it provide an voltage 24.7 mV when worn on arm room temperature. textile-based sensor exhibits detection (0.7 K) response time (2.49 s). Integrating Ag2Se onto enables utilization multipixel touchpads writing communication. Additionally, these sensors be incorporated into gloves accurately detect surrounding objects' temperatures. This thread not only facilitates but also establishes solid foundation widespread application multifunctional electronics.

Dynamic polyimines are a class of fascinating dynamic polymers with recyclability and reparability owing to their reversible Schiff-base reactions. However, balancing the properties mechanical strength presents major challenge due dissociative associative nature imine bonds. Herein, we introduced bulky fluorene groups polyether amine into skeleton polyimine networks achieve tradeoff in comprehensive properties. The resulting (Cardo-DPIs) were successfully synthesized by combining rigid diamine 9,9-bis(4-aminophenyl)fluorene flexible amine, demonstrating high tensile 64.7 MPa. Additionally, Cardo-DPIs films more content exhibited higher water resistance, glass transition temperature wear-resisting ability. Moreover, not only efficiently underwent thermal reshaping, but also excellent self-healing capabilities chemical degradation acidic solutions. Furthermore, can fully closed-loop recovery free solution for 2 h at room temperature. This study broadens scope materials promotes balanced development functional
