Core–Sheath Heterogeneous Interlocked Conductive Fiber Enables Smart Textile for Personalized Healthcare and Thermal Management

Small, Journal Year: 2023, Volume and Issue: 20(23)

Published: Dec. 26, 2023

Abstract Whereas thermal comfort and healthcare management during long‐term wear are essentially required for wearable system, simultaneously achieving them remains challenge. Herein, a highly comfortable breathable smart textile personal is developed, via assembling stimuli‐responsive core–sheath dual network that silver nanowires(AgNWs) core interlocked graphene sheath induced by MXene. Small MXene nanosheets with abundant groups proposed as novel “dispersant” to according “like dissolves like” theory, while acting “cross‐linker” between AgNWs networks filling the voids them. The heterogeneous conductive fiber “cross‐linking” exhibits reliable response various mechanical/electrical/light stimuli, even under large mechanical deformations(100%). fiber‐enabled can adapt movements of human body seamlessly, convert these deformations into character signals accurate monitoring rapid response(440 ms). Moreover, excellent Joule heating photothermal effect instant energy harvesting/storage stimuli‐response process, which be developed self‐powered dynamic camouflage when integrated phase change thermochromic layer. fibers/textiles structures hold great promise in personalized management.

Design of Sustainable Self‐Healing Phase Change Materials by Dynamic Semi‐Interpenetrating Network Structure

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(7)

Published: Oct. 31, 2023

Abstract The design of sustainable self‐healing phase change materials (SHPCMs) remains challenging depending on fatty alcohols without compromising high enthalpy efficiency. Herein, the semi‐interpenetrating network (semi‐IPN)‐based SHPCMs are developed by introducing dynamic disulfide crosslinking polyurethane networks and as components in a semi‐IPN structure, enabling combination ultrahigh efficiency ≈100% excellent ability with 99% mechanical stain healing latent heat (61.6–144.3 J g −1 ) temperature (29.2–64.2 °C) can be readily adjusted type content SHPCMs. present thermal reliability, shape stability, solid‐like rheological properties benefiting from advantage structure. endowed tunable stress (1.23–6.16 MPa) strain (5.77–379.48%). More importantly, nearly completely self‐healed after stimulus, complying Arrhenius model, low activation energy 33.831 kJ mol . This innovative strategy opens new avenues for preparing efficient durable storage efficiency, ability, components, broadening their potential applications.
