The structural disorder of the black butterfly assists in capturing sunlight across a wider spectral and angular range, injecting infinite vitality for omnidirectional stimuli-responsive wave-absorbing materials. Here, disordered micro-pores responding to terahertz (THz) waves through electromagnetic simulations, then prepared via ice templating technology are analyzed optimized. customized aerogel makes possible perfect response property with incidence-angle-insensitive ultra-broadband. Ti3C2Tx MXene/carboxymethyl cellulose aerogels realize excellent shielding effectiveness exceeding 70.32 dB reflection loss more than 43.02 over frequency range 0.3-1.5 THz. Tailoring orientation anisotropic functions as versatile dynamic modulation approach along propagation direction. porous structure moderate conductivity gradually triggers resonance effect cavity, approximating sphere (pore) waveguide system (tube). Ultimately, gradient impedance is proposed integrating THz-infrared stealth, hydrophobicity, mechanical strength. This inspired biomimetic strategy will also enable various applications such imaging, line-of-sight telecommunication, information encryption, space exploration.

Abstract Excessive electromagnetic pollution caused by waves can interfere with the normal use of electronic devices or cause unnecessary damage to human health. Although conductive polymer composites (CPCs) are used replace traditional metals as an effective strategy for managing undesirable waves, CPCs have a non‐negligible trade‐off in enhancement interference (EMI) shielding effectiveness and absorption coefficient because their reflection‐dominated EMI mechanism. Therefore, alleviate secondary pollution, absorption‐dominated asymmetric structures urgently needed. Recently, structural designs advanced significantly, but seldom been summarized discussed detail. Consequently, this review first systematically summarizes current progress after brief clarification about necessity configuration structure design. Afterward, various fiber, layered, porous, composite described. Besides, versatility is briefly introduced. Finally, challenges prospects proposed guide future advancement field.

Ink printing can be considered a desirable production method for mass manufacturing inexpensive electronic textiles. Copper nanowires (CuNWs) have attracted enormous attention due to preponderant electric conductivity, mechanical properties, and large abundance in recent years. Unfortunately, low dispersibility, poor binding, incompatibility of CuNWs greatly limit their development conductive inks. Herein, green CuNW ink with high conductivity durability was reported, which couples tannic-polyethylenimine (TA-PEI) modified (TA-PEI@CuNW) heterostructure as "brick" carboxymethyl cellulose (CMC) acting "mortar" inspired by the "brick–mortar" structure pearls. The exhibits splendid adhesion strength on textiles, attributed abundant hydrogen bonding sites between CMC TA-PEI@CuNWs. obtained printed fabric also shows superb (sheet resistance Ra = 3.33 Ω·sq–1) bending (withstanding 1500 cycles). Furthermore, presented exceptional application potential Joule heating (112.8 °C at 1.5 V voltage) electromagnetic shielding (shielding efficiency SET 50.488 dB). We think that may provide insight into personal thermal management fabrics.
