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

Direct Assembly of Aerogel Micro‐Nanofiber/MXene Sponges with Dual‐Network Structures for All‐Day Personal Heating

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(27)

Published: Feb. 21, 2024

Abstract Maintaining human body temperature under low is crucial to well‐being, thereby urgently requiring for high‐performance warmth retention materials. However, designing such materials with both mechanical robustness and warming up the complex changing outdoor environments remains challenging. Here, a dual‐network structured aerogel micro‐nanofiber/MXene sponge directly synthesized by synchronous occurrence of electrospinning electrospraying. Tailoring phase inversion solution jet creates micro‐nanofibers highly porous structures, which exhibit nanoscale aperture (30–60 nm) high single fiber surface aera (56.5 m 2 g −1 ). Under strong hydrogen bonding interaction, structures are constructed chemical entanglement between self‐assembled MXene networks, achieving robust stretchable compressible property. The nanopores cause Knudsen effect suppress slippage air molecules, enhancing unique capacity block heat energy. Further integrating passive radiative heating active performance as‐designed offers an all‐day personal system rise skin over 3.5 °C. This work may provide new candidates applications within aerospace, energy, transportation, building.
