Ultralight Three‐Layer Gradient‐Structured MXene/ Reduced Graphene Oxide Composite Aerogels with Broadband Microwave Absorption and Dynamic Infrared Camouflage

Small, Journal Year: 2024, Volume and Issue: unknown

Published: May 2, 2024

Abstract Infrared and radar detectors posed substantial challenges to weapon equipment personnel due their continuous surveillance reconnaissance capabilities. Traditional single‐band stealth devices are insufficient for dual‐band detection in both infrared microwave bands. To overcome this limitation, a gradient‐structured MXene/reduced graphene oxide (rGO) composite aerogel (GMXrGA) is fabricated through two‐step bidirectional freeze casting process, followed by freeze‐drying thermal annealing. GMXrGA exhibits distinct three‐layered structure, with each layer playing crucial role absorption. This deliberate design amplifies the efficiency of absorption material's effectiveness dynamic camouflage. displays an ultralow density 5.2 mg∙cm −3 demonstrates exceptional resistance compression, enduring 200 cycles at maximum strain 80%. Moreover, it shows superior performance, minimum reflection loss ( RL min ) –60.1 dB broad effective bandwidth EAB 14.1 GHz (3.9–18.0 GHz). Additionally, low conductivity (≈26 mW∙m −1 ∙K camouflage capabilities within temperature range 50–120 °C, achieving rapid concealment 30 s. Consequently, they hold great potential diverse applications, including intelligent buildings, wearable electronics, equipment.

Published: April 12, 2024

Abstract 2D transition metal carbide/nitride (MXene) show significant potential for fabricating flexible wearables due to its outstanding electroactive characteristic. However, the complex processes in rheology regulation and easy agglomeration of MXene nanosheets hinder their applications as inks homogeneous printing coating. Herein, an gel‐ink with a low concentration (20 mg mL −1 ) using poly(3,4‐ethylenedioxythiophene):poly(sodium 4‐styrenesulfonate) (PEDOT:PSS) dopant conductive binder is developed. The dopamine‐involved modification PEDOT:PSS doping together promote formation ordered lamellar structure nanosheets, turn can regulate interconnected electronic PEDOT:PSS, which enables from micellar linear structures. Through adjusting combination ratio dopamine‐modified (MD) viscosity (MDP) tunable within 1–10 4 Pa·s realize scalable other processing. Screen‐printing MDP endows textiles excellent stability while retaining inherent wearability original fabric. With high conductivity (109.6 S m mid‐infrared emissivity (0.34), decorated exhibit remarkable multi‐protective abilities. This work provides novel strategy formulating versatile that will facilitate large‐scale fabrication high‐performance personal wearable textiles.
