Here, we report an NUI based on an intelligent fabric bracelet empowered with wide-range pressure detectability, enabling invisible and efficient human–machine interaction. The wide-range pressure-sensing ability of the fiber-based pressure sensor can be attributed to the coupling mechanism of contact resistance change and quantum tunneling effect. The fiber-based sensor array is then integrated with a miniaturized wireless flexible printed circuit board, forming an intelligent and compact fabric bracelet system for natural interactive applications in wireless smart home control and virtual reality.

The key to resolving this bottleneck is leveraging strong hydrogen bonding to reduce the enthalpy of evaporation for water molecules and inputting environmental energy. This study presents a novel approach for reducing the enthalpy of vaporization by introducing a hydrophilic inorganic material Al(H₂PO₄)₃ (AP) on the surface of cellulose nanofibers (CNF) to form an inorganic‒organic hydrogen-bonded network in cellulose-based hydrogels (labeled 3DL Metagel). This network structure accelerates the diffusion of water molecules between CNF, as confirmed by molecular dynamics simulations. Specifically, inspired by multiple biological traits found in nature, the 3DL Metagel evaporator integrates a lotus shape, Janus wettability (the superhydrophilic lotus-like flower with hydrophobic lotus-like leaves) and plant transpiration, resulting in superior water evaporation rates of up to 3.61 kg·m⁻²·h⁻¹ under 1.0 solar radiation (exceeding the limit of two-dimensional evaporators). The unique lotus shape enables 3DL Metagel to draw additional energy from the environment during desalination, resulting in a maximum water evaporation efficiency of 94.94%. The dual porous structure with Janus wettability endows the evaporator with self-floating ability and a unidirectional salt ion reflux channel during the evaporation process, providing a salt-resistant technology for seawater desalination. Noteworthy, evaporator can be used for efficient outdoor water purification in arid areas with extremely low humidity and is biodegradable and biocompatible. The integration of an inorganic‒organic hydrogen-bonded cross-linked network and biomimetic features achieves high-efficiency photothermal water evaporation, offering novel insights for the rational design of efficient evaporators for solar desalination and wastewater purification.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 3","pages":"748 - 761"},"PeriodicalIF":17.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanofiber aerogels with ultralight weight and high porosity have recently emerged as promising candidates. However, the weak inter-fiber interaction hampers the robustness of the three-dimensional network, resulting in poor overall mechanical properties that hinder their wide adoption. Herein, we propose a novel template-anchored strategy for constructing polyimide hybrid nanofiber aerogels. By utilizing self-supporting chitosan as a sacrificial template, polyimide (PI) nanofibers are directionally interconnected by chemical pre-anchoring and heat treatment, which endows the three-dimensional fiber network with good structural stability. These directly assembled nanofiber aerogels exhibit an adjustable low-density range (12.3–31.5 mg/cm³), excellent compressive resilience and fatigue resistance (with only 7.2% permanent deformation after 100 cycles at 60% strain), demonstrating good shape recovery. Moreover, the complex nanofiber pathway and porous network structure contribute to superior thermal insulation performance with low thermal conductivity (28.5–31.8 mW m⁻¹ K⁻¹). Furthermore, the incorporation of polyimide and silica (SiO₂) imparts these hybrid aerogels with remarkable high-temperature resistance and flame retardancy. This study introduces and validates a novel approach for obtaining superelastic and lightweight aerogels, highlighting its promising potential in the realm of high-temperature thermal insulation.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 3","pages":"799 - 810"},"PeriodicalIF":17.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, most current passive radiative cooling fabrics overlook their inherent thermal conductivity, resulting in ineffective heat transfer from human skin to the environment. Herein, by constructing highly anisotropic thermal conductive thermoplastic polyurethane/boron nitride nanosheet (TPU/BNNS) fabrics via one-step electrospinning, thermal conductive cooling mechanism was introduced into passive radiative cooling fabrics. The stacked TPU/BNNS nanofibers with aligned BNNS along the fiber direction and the porous fiber network with high contact thermal resistance resulted in high thermal conductivity along the in-plane direction but low thermal conductivity along the out-of-plane direction. This high anisotropy enables rapid heat transfer along the in-plane direction to dissipate heat while blocking external heat penetration along the out-of-plane direction, thus achieving an effective conductive cooling effect. Moreover, the incorporation of BNNS increased the scattering sites for solar radiation, further improving the fabric’s solar reflectivity to 95%. Combined with the high emissivity (92.9%) provided by the intrinsic groups of TPU and BNNS, the fabric demonstrates excellent radiative cooling ability. Therefore, under the dual action of passive radiative cooling and conductive cooling, the TPU/BNNS fabric achieved a sub-environmental cooling of 12.4 °C and a personal cooling of 10.7 °C. Along with excellent breathability, stretchability, and waterproof properties, the TPU/BNNS fabric exhibits outstanding potential for outdoor personal thermal management applications.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 3","pages":"841 - 852"},"PeriodicalIF":17.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
