However, existing fabrics fail to provide both effective personal thermal management and electromagnetic interference (EMI) shielding. To address this challenge, an asymmetric gradient porous fabric (AGPF) is developed using a delayed evaporation-induced phase separation strategy. The AGPF consists of gradient porous polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS) and transversely oriented liquid metal (LM) networks with wrinkled structures at the bottom. Due to the complete sedimentation of liquid metal, the gradient porous SEBS maintains excellent solar reflectivity of 93.9% and atmospheric window infrared emissivity of 94.7%. Upon activation by pre-stretching, LM imparts AGPF high electrical conductivity and enhanced stretchability to the AGPF, resulting in excellent EMI shielding effectiveness of 80.6 dB and electrical heating performance. Outdoor cooling tests further confirmed that AGPF achieves sub-ambient cooling of ≈9.5 °C. Moreover, AGPF exhibits dynamically tunable thermal management and EMI shielding performance across a strain range of 0% to 200%, adapting to complex outdoor environments. The design of AGPF provides an advanced solution to protect individuals from the dual threats posed by urban heat island effects and electromagnetic pollution.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"93 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666641","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}

However, the production of uniform and dense thick films as well as achieving efficient carrier transport over tens of microns in thick PVK films, remain major challenges for highly sensitive X-ray detection. Herein, an innovative vacuum-assisted blade coating strategy is proposed using PVK inks that strictly controls the nucleation and growth of PVKs to prepare large-area, high-quality MAPbI₃ homojunction thick films. Arising from the formation of a type II homojunction between the top and bottom PVK layers, and effective reduction of the density of defect states, the resultant homojunction film exhibits impressive performances, including an increase in carrier lifetime from 1272 to 9335 ps, an increase in surface photovoltage change from 93 to 386 mV, and nearly three times higher carrier mobility-lifetime product compared with pristine NMP-PVK film. Consequently, the X-ray detector based on homojunction film demonstrates a high sensitivity of 1.3 × 10⁵ µC Gy_air⁻¹ cm⁻², surpassing the most previously reported values for X-ray detector using blade coating method. This research provides a convenient approach for preparing large-area PVK thick films and establishes a solid foundation for the development of X-ray detection.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"92 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666614","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}

In this study, a FeCoP/TiN/CP(carbon paper) nanoarray electrode with exceptional hydrogen evolution reaction (HER) activity and durability at the industrial current density is successfully fabricated by engineering electronic coupling at the N─transition metal (TM, Co/Fe)─P interfacial bridge. Remarkably, the FeCoP/TiN/CP electrode requires only an overpotential of 129 mV (alkaline fresh water) and 152 mV (alkaline seawater) to achieve a current density of 500 mA cm⁻², and stable operation is demonstrated for 2000 h in alkaline freshwater and 340 h in alkaline seawater at 500 mA cm⁻² with negligible degradation. The superior HER performance stems from the unique nanoarray architecture and the phase interface N─TM(Co/Fe)─P bridge bonding, which enhances wettability, facilitates bubble release, and provides resistance to seawater corrosion. Theoretical calculations demonstrate that the interfacial N─TM(Co/Fe)─P bridging regulates the electronic structure of FeCoP, promoting water adsorption and dissociation, while optimizing the intermediate H* free energy. Furthermore, the covalent nature of the N-TM(Co/Fe)-P bridging, along with the strengthened Co/Fe-P bonds, contributes to the superior stability of FeCoP/TiN/CP.

This study introduces a synergistic ion transport strategy integrating short- and long-range pathways for enhanced sodium-ion mobility. Electrospun ceramic nanofibers, modified with acylamino groups, form interfacial transport channels, while deep eutectic electrolytes (DEE) confined within these channels enable temperature-independent, long-range ion transport. Surrounding polymer electrolytes facilitate short-range ion migration between the polymer and DEE. This composite electrolyte achieves high ionic conductivity (0.088 mS cm⁻¹ at −50 °C) and exceptional rate performance up to 20 C. The structure confines the DEE to ceramic fiber interfaces, preventing the formation of a gel-like state due to DEE-polymer mixing, and maintaining robust mechanical properties. The DEE interacts with polar groups on both the ceramic fibers and polymer matrix, reducing side reactions with the metal anode and improving cycle stability. The electrolyte retains 92.2% capacity retention at −30 °C after 100 cycles and 97.7% after 1000 cycles at 26 °C, with stable performance over 10 000 cycles at 5 C.

Herein, a strategy involving the addition of a foaming agent (NH₄Cl) to the precursor is adopted, which significantly enhances the penetration of the molten salt during the ionothermal synthesis of crystalline carbon nitride. This results in a more uniform internal structural unit and fewer detrimental structural defects (terminal amine groups and hydrogen bonds formed by these groups) in crystalline carbon nitride due to the transformation from the triazine-heptazine mixed phase to the heptazine phase. This improvement enables the photocatalyst, upon loading of cocatalysts, to maximally utilize photogenerated electrons and holes, establishing a smooth pathway for surface protonation and electron-proton coupling. The results show that the photocatalytic hydrogen production rate reaches 8.67 mmol g⁻¹ h⁻¹ and exhibits a high apparent quantum efficiency of 22.1% (λ = 400 nm) for hydrogen evolution. This study elucidates the relationship between molten salt penetration and the crystal structure of carbon nitride during the ionothermal synthesis process.
