“…As shown in Figure a–c, for a pure MF, as the MXene concentration increases, the square resistance of MF decreases from 53.7 to 5.4 Ω. This reduction leads to the transition of electrons, thus increasing the ohmic loss . Also, the ε′ and ε″ values increase, indicating an improvement in the electricity storage and loss capacity, respectively .…”

A layer−layer composite impedance-gradient structure can achieve good impedance matching characteristics. However, its impedance step and poor bonding fastness between layers are not conducive to the maximization of electromagnetic wave absorption. Based on the concentration-diffusion mechanism of interfacial freezing of conductive polymers, combined with the high conductivity of MXene nanosheets, a fabric structure with a continuous impedance gradient along the thickness direction was creatively constructed. Its intrinsic impedance from the bottom to the top of the fabric increases gradually to a value close to the freespace impedance. The minimum reflection loss of the produced MP-IIGF-1 is −31.98 dB, and its effective absorption bandwidth can cover the entire X-band (4.2 GHz). This work not only realizes the composite of nanoabsorbing agents but also proposes a method for implementing a continuous impedance gradient, thus providing a design concept for a broadband absorbing fabric and its impedance adjustment.

Fibers, originating from nature and mastered by human, have woven their way throughout the entire history of human civilization. Recent developments in semiconducting polymer materials have further endowed fibers and textiles with various electronic functions, which are attractive in applications such as information interfacing, personalized medicine, and clean energy. Owing to their ability to be easily integrated into daily life, soft fiber electronics based on semiconducting polymers have gained popularity recently for wearable and implantable applications. Herein, we present a review of the previous and current progress in semiconducting polymer-based fiber electronics, particularly focusing on smart-wearable and implantable areas. First, we provide a brief overview of semiconducting polymers from the viewpoint of materials based on the basic concepts and functionality requirements of different devices. Then we analyze the existing applications and associated devices such as information interfaces, healthcare and medicine, and energy conversion and storage. The working principle and performance of semiconducting polymer-based fiber devices are summarized. Furthermore, we focus on the fabrication techniques of fiber devices. Based on the continuous fabrication of one-dimensional fiber and yarn, we introduce two-and three-dimensional fabric fabricating methods. Finally, we review challenges and relevant perspectives and potential solutions to address the related problems.

The development of wearable multifunctional electromagnetic protective fabrics with multifunctional, low cost, and high efficiency remains a challenge. Here, inspired by the unique flower branch shape of “Thunberg’s meadowsweet” in nature, a nanofibrous composite membrane with hierarchical structure was constructed. Integrating sophisticated 0D@2D@1D hierarchical structures with multiple heterointerfaces can fully unleash the multifunctional application potential of composite membrane. The targeted induction method was used to precisely regulate the formation site and morphology of the metal–organic framework precursor, and intelligently integrate multiple heterostructures to enhance dielectric polarization, which improves the impedance matching and loss mechanisms of the electromagnetic wave absorbing materials. Due to the synergistic enhancement of electrospinning-derived carbon nanofiber “stems”, MOF-derived carbon nanosheet “petals” and transition metal selenide nano-particle “stamens”, the CoxSey/NiSe@CNSs@CNFs (CNCC) composite membrane obtains a minimum reflection loss value (RLmin) of -68.40 dB at 2.6 mm and a maximum effective absorption bandwidth (EAB) of 8.88 GHz at a thin thickness of 2.0 mm with a filling amount of only 5 wt%. In addition, the multi-component and hierarchical heterostructure endow the fibrous membrane with excellent flexibility, water resistance, thermal management, and other multifunctional properties. This work provides unique perspectives for the precise design and rational application of multifunctional fabrics.
