ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(13), P. 16712 - 16723

Published: March 20, 2024

The fabrication of carbon aerogels with ultralow density, high electrical conductivity, and ultraelasticity still remains substantial challenges. This study utilizes electrospun polyimide aerogel as the source to fabricate flexible nanofibrous (PI-CNA) capable multifunctional applications. lightweight PI-CNA based piezoresistive sensor shows a wide linear range (0–217 kPa), rapid response/recovery time, fatigue resistance (12,000 cycles). More importantly, superior pressure sensing enables for all-range healthcare sensing, including pulse monitoring, physiological activity detection, speech recognition, gait recognition. Moreover, EMI SE A coefficient reach 45 dB 0.62, respectively, indicating outstanding absorption dominated shielding effects due multiple reflections absorption. Furthermore, exhibits satisfying Joule heating performance up 120 °C response time (10–30 s) under low supply voltages (1.5–5 V) possesses sufficient reliability repeatability in long-term repeated heating/cooling cycles. fabricated significant potential applications wearable technologies, energy conversion, electronic skin, artificial intelligence.

Multi‐Scale MXene/Silver Nanowire Composite Foams with Double Conductive Networks for Multifunctional Integration

Advanced Science, Journal Year: 2024, Volume and Issue: 11(30)

Published: June 13, 2024

Abstract With the onset of 5G era, wearable flexible electronic devices have developed rapidly and gradually entered daily life people. However, vast majority research focuses on integration functions performance improvement, while ignoring electromagnetic hazards caused by devices. Herein, 3D double conductive networks are constructed through a repetitive vacuum‐assisted dip‐coating technique to decorate 2D MXene 1D silver nanowires melamine foam. Benefiting from unique porous structure multi‐scale interconnected frame, resultant composite foam exhibited high electrical conductivity, low density, superb interference shielding (48.32 dB), Joule heating (up 90.8 °C under 0.8 V). Furthermore, single‐electrode triboelectric nanogenerator (TENG) with powerful energy harvesting capability is assembled combining an ultra‐thin Ecoflex film polyvinylidene fluoride film. Simultaneously, foam‐based TENG can also be considered reliable sensor for monitoring activity patterns in different parts human body. The versatility scalable manufacturing high‐performance foams will provide new design ideas development next‐generation
