Highly Elastic Spongelike Hydrogels for Impedance-Based Multimodal Sensing

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

Hydrogel-based sensors have been widely studied for perceiving the environment. However, simplest type of resistive still lacks sensitivity to localized strain and other extractable data. Enhancing their expanding functionality perceive multiple stimuli simultaneously are highly beneficial yet require optimal material design proper testing methods. Herein, we report a elastic, sponge-like hydrogel its derived multimodal iontronic sensor. By unidirectional freeze casting poly(vinyl alcohol) (PVA) with electrospun cellulose nanofibers (CNF), hierarchical structure aligned PVA channels supported by interlaced CNF tangles is created. The ensures both efficient mass transport good elasticity, enhancing reversible compressibility ionic conductivity. Combining this sponge impedance-based measurement methods allows development capable detecting local strain, position, object-in-contact. Integrating these sensing capabilities, two-dimensional small motion monitor, 3D input interface, identification gripper demonstrated. This study provides simple approach versatile sensors.

A Transparent Polymer-Composite Film for Window Energy Conservation

Nano-Micro Letters, Год журнала: 2025, Номер 17(1)

Опубликована: Фев. 17, 2025

Abstract As living standards improve, the energy consumption for regulating indoor temperature keeps increasing. Windows, in particular, enhance brightness but also lead to increased loss, especially sunny weather. Developing a product that can maintain while reducing is challenge. We developed facile, spectrally selective transparent ultrahigh-molecular-weight polyethylene composite film address this trade-off. It based on blend of antimony-doped tin oxide and then spin-coated hydrophobic fumed silica, achieving high visible light transmittance (> 70%) shielding rates ultraviolet 90%) near-infrared 70%). When applied acrylic window containers placed outside, cause 10 °C drop compared pure polymer film. Moreover, building simulations, annual savings could be between 14.1% ~ 31.9% per year. The development energy-efficient eco-friendly films crucial promoting sustainability environment.

Low‐Cost Hyperelastic Fuller‐Dome‐Structured Nanocellulose Aerogels by Dual Templates for Personal Thermal Management

Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Окт. 22, 2024

It is critically important to maintain the body's thermal comfort for human beings in extremely cold environments. Cellulose nanofibers (CNF)-based aerogels represent a promising sustainable material heat retention because of their renewability and low conductivity. However, CNF-based often suffer high production costs due expensive CNF, poor elasticity and/or unsatisfactory insulation owing improper microstructure design. Here, facile dual-template strategy reported prepare low-cost, hyperelastic, superhydrophobic Fuller-dome-structured CNF aerogel (CNF@PU) with The combination air template by foaming process ice enables formation dome-like CNF@PU aerogel, which serves as rope bars while inexpensive polyurethane (PU) acts joints. combines ultra-elasticity, conductivity (24 mW m

Опубликована: Март 19, 2025

Abstract Radiative cooling fabric creates a thermally comfortable environment without energy input, providing sustainable approach to personal thermal management. However, most currently reported fabrics mainly focus on outdoor cooling, ignoring achieve simultaneous both indoors and outdoors, thereby weakening the overall performance. Herein, full-scale structure with selective emission properties is constructed for indoor cooling. The achieves 94% reflectance performance in sunlight band (0.3–2.5 µm) 6% mid-infrared (2.5–25 µm), effectively minimizing heat absorption radiation release obstruction. It also demonstrates 81% radiative atmospheric window (8–13 25% transmission μm), 60 26 W m −2 net power outdoors indoors. In practical applications, excellent human temperatures 1.4–5.5 °C lower than typical polydimethylsiloxane film.
