With the continuous development of small and medium-sized electronic devices, which bring convenience to people’s lives, electromagnetic wave (EMW) pollution has emerged as a significant issue. The materials with interference (EMI) shielding capabilities for protection against harmful radiation plays vital role. Currently, wide range multifunctional, lightweight EMI have been created address various environmental requirements. However, single material difficult meet requirements high-speed transmission equipment because when such devices operate at high speeds, they typically generate elevated temperatures, excessive further exacerbates heat accumulation, reducing both efficiency lifespan. Therefore, thermal management is essential lower operating temperatures ensure optimal performance. Phase change (PCMs) are known storing large amount energy, potential in management, so flexible phase composites (PCCs) emerged. This review provides detailed examination based on fillers, PCMs latest advancements developing new PCCs. Finally, we suggest some research directions PCCs, hoping contribute rapid advancement next-generation electronics, human artificial intelligence.

Permeable, Stretchable, and Recyclable Cellulose Aerogel On-Skin Electronics for Dual-Modal Sensing and Personal Healthcare

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 12, 2025

Flexible on-skin electronics present tremendous popularity in intelligent electronic skins (e-skins), healthcare monitoring, and human-machine interfaces. However, the reported e-skins can hardly provide high permeability, good stretchability, large sensitivity are limited long-term stability efficient recyclability when worn on human body. Herein, inspired from skin, a permeable, stretchable, recyclable cellulose aerogel-based system is developed by sandwiching screen-printed silver sensing layer between biocompatible CNF/HPC/PVA (cellulose nanofiber/hydroxypropyl cellulose/poly(vinyl alcohol)) aerogel hypodermis permeable polyurethane as epidermis layer. The displays tensile strength of 1.14 MPa strain 43.5% while maintaining permeability. embrace appealing performances with (gauge factor ≈ 238), ultralow detection limit (0.1%), fast response time (18 ms) under stimulus. Owing to disconnection reconnection microcracks layer, both strain/humidity thermal be easily achieved. further integrated into an mask for patient-centered power supply system, switching control device, wireless Bluetooth module. Moreover, prepared enables wearing skin without irritation, all components recaptured/reused water. This material strategy highlights potential next-generation permeability environmental friendliness.

Self-Driven, Monopolar Electrohydrodynamic Printing via Dielectric Nanoparticle Layer

Nano Letters, Год журнала: 2024, Номер 24(31), С. 9511 - 9519

Опубликована: Июль 23, 2024

Electrohydrodynamic printing holds both ultrahigh-resolution fabrication capability and unmatched ink-viscosity compatibility yet fails on highly insulating thick/irregular substrates. Herein, we proposed a single-potential driven electrohydrodynamic process with submicrometer resolution arbitrary nonconductive targets, regardless of their geometric shape or sizes, via precoating an ultrathin dielectric nanoparticle layer. Benefiting from the favorable Maxwell-Wagner polarization, reversely polarized spot brought about significant drop (∼57% for ceramics) in operation voltage as its induced electric field negligible residual charge accumulation. Thus, ordered micro/nanostructures line widths down to 300 nm were directly written at stage speed low 5 mm/s, silver features width ∼2 μm interval ∼4 achieved substrates separately. Flexible sensors curved heaters then high-precision printed demonstrated successfully, presenting this technique huge potential fabricating flexible/conformal electronics 3D structures.
