Bioinspired wood-like coaxial fibers based on MXene@graphene oxide with superior mechanical and electrical properties

Abstract

MXenes, a new class of two-dimensional materials with excellent performance, are promising materials for wearable energy storage devices. However, the lack of sufficient interaction between various MXene particles makes it...

Two‐dimensional MXenes: New frontier of wearable and flexible electronics

“…Inspired by nature, several functional nanostructures have been fabricated by researchers to realize their performance in soft electronics, skin-inspired microelectronics, sensors, and actuators. 117,[152][153][154][155][156] Among these, bioinspired nacre, leaf-like structures, and polymeric woods have been widely explored. 157,158 Especially, nacre-like structures induce exceptional mechanical reinforcing effects, thereby producing materials with high strength and stiffness.…”
