Abstract Wearable sensing technologies have witnessed rapid development in recent years due to their accessibility, functionality, and affordability. However, heat accumulation electromagnetic interference electronic components adversely affect the performance seriously damage human health. Herein, cellulose nanofibers (CNFs)‐based composites with high thermal conductivity (TC) excellent (EMI) shielding are prepared using CNFs as templates followed by coating tannic acid non‐covalent 3‐aminopropyltriethoxysilane covalent co‐modified graphene nanoplatelets (denoted mGNPs) through a simple electrostatic self‐assembly method. The subsequent hot‐pressing process yield order layer mGNPs CNFs‐based distributed along orientation close contact CNFs, fashion similar nervous system. resulting reveal TC of 136.2 W/(m·K) superior EMI effectiveness 105 dB. Thus, they used wearable sensors based on triboelectric effect monitor health real‐time, well express emotion Morse code. In sum, proposed strategy provides an avenue prolong service life flexible ensure safe use, promising for future wisdom healthcare smart robotics.

Robust Solid–Solid Phase Change Coating Encapsulated Glass Fiber Fabric with Electromagnetic Interference Shielding for Thermal Management and Message Encryption

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 9, 2024

Abstract Electromagnetic interference (EMI) shielding composites with both thermal response/management functions and message transfer/encryption behavior are ideal for use in fields such as aerospace, construction engineering, military equipment. In this work, a self‐cross‐linking supramolecular solid–solid phase change polyethylene glycol (ScPEG) coating is prepared based on multiple hydrogen bonds, which used encapsulating glass fiber fabric (GFF) modified silver nanowires (AgNWs). The obtained through the hydrolysis‐condensation of PEG reactive silanol end group. Polyethylene molecular chains can store release heat by switching between crystalline amorphous state. groups form networks physical cross‐linking resulting an excellent stability. particular, bonds ScPEG AgNW‐modified GFF (A‐GFF) enhance interfacial interactions, robust structure enables efficient stress transfer. ScPEG‐coated A‐GFF achieve tensile strength up to 191 MPa tunable EMI effectiveness (SE) 40 72 dB depending number layers. Moreover, exhibits flexible response characteristic, outstanding management capability, potential encryption behavior.

Abstract Recently, there has been a growing demand for ultra‐thin carbonized wood films (CWF) with high shielding efficiency (SE) to replace non‐renewable alternatives. Researchers aim enhance electromagnetic (EM) wave absorption and improve interference (EMI) SE in CWF materials reduce secondary pollution from reflected EM waves. In this work, the composite film (CWF/EP/Co) thickness of 120 µm through process hot‐pressing carbonizing soaked mixed solution water‐borne epoxy (EP) Co/Zn‐MOF (ZIF‐67/8) is obtained. The CWF/EP/Co exhibits excellent conductivity (105 S cm −1 ) demonstrates an EMI (73 dB) at 200 thickness. Remarkably, specific effectiveness (SSE/t) reached 15833.3 dB·cm 2 ·g X‐band, making it highest reported value among all wood‐derived materials. have coefficient (A) 0.4, indicating their absorbing Furthermore, effect large‐scale wallpaper (170 mm×170 mm) confirmed by finite element analysis. Additionally, good mechanical properties effective Joule heating performance. This shows promise applications such as buildings smart homes, providing warming effects.
