Ultrathin Titanium Carbide (MXene) Films for High‐Temperature Thermal Camouflage

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(35)

Published: June 19, 2021

Abstract Thermal camouflage has attracted increasing attention owing to the rapid development of infrared (IR) surveillance technologies. Various materials and systems have been developed date, but realization high‐temperature thermal using ultrathin film/coating remains a great challenge; this is significance, especially for IR stealth in military equipment. This work demonstrates series Ti 3 C 2 T x MXene films (as low as 1 µm) with superior indoor/outdoor performance: wide temperature range (from below −10 °C over 500 °C), large reduction radiation (exceeding 300 objects temperatures long‐term or fire stability, multifunctionality including disguised Joule heating capability, high electromagnetic interference shielding efficiency. The performance film attributed its mid‐IR emissivity (0.19), which comparable that stainless steel far other 2D nanomaterials, such graphene. multifunctional prepared through simple vacuum‐assisted filtration provide feasible method efficient films, demonstrating promise camouflage, stealth, counter‐surveillance, security protection.

Ti₃C₂T_x MXene-Decorated Nanoporous Polyethylene Textile for Passive and Active Personal Precision Heating

ACS Nano, Journal Year: 2021, Volume and Issue: 15(7), P. 11396 - 11405

Published: June 24, 2021

Heating the human body to maintain a relatively constant temperature is pivotal for various functions. However, most of current heating strategies are energy-consuming and energy-wasting cannot cope with complex changing environment. Developing materials systems that can heat precisely via an efficient energy-saving approach no matter indoors/outdoors, day/night, sunny/cloudy highly anticipated mitigating growing energy crisis global warming but still great challenge. Here, we demonstrate low mid-infrared radiative (mid-IR) emissivity characteristic Ti3C2Tx MXene then apply it energy-free passive (PRH) on body. Our strategy realized by simply decorating cheap nanoporous polyethylene (nanoPE) textile MXene. Impressively, as-obtained 12 μm thick MXene/nanoPE shows mid-IR 0.176 at 7–14 outstanding indoor PRH performance body, which enhances 4.9 °C compared traditional 576 cotton textile. Meanwhile, exhibits excellent active outdoor solar indoor/outdoor Joule capability. The three modes integrated in this wearable system be switched easily or combined arbitrarily, making thin able scenarios like sunny/cloudy, providing multiple promising solutions future all-day personal precision thermal management.
