High-strength, low infrared-emission nonmetallic films for highly efficient Joule/solar heating, electromagnetic interference shielding and thermal camouflage

Abstract

High-strength nonmetallic material with low infrared (IR) emission is rare in nature yet highly anticipated especially in military and aerospace fields for thermal camouflage, infrared stealth, energy-saving heating. Here, we...

Achieving fast interfacial solar vapor generation and aqueous acid purification using Ti3C2TxMXene/PANI non-woven fabrics

“…39,40 As a result, even MP0 presented a high absorption of 85.8% on average over the AM 1.5G solar spectrum. Note that Ti 3 C 2 T x has been recently reported as an infrared white material with a low infrared emissivity of about 10%, 41,42 which further verified that the absorption of sunlight could be largely enhanced by assembling Ti 3 C 2 T x nanosheets into porous non-woven fabric with micro-crumples. The highest absorption was realized by MP2, which could reach 88.3% on average.…”

Research Progress with Membrane Shielding Materials for Electromagnetic/Radiation Contamination

“…Zhang et al [ 175 ] have suggested that wave interference occured during the course of multiple reflections, and its possible resonance characteristics would promote the absorption of specific electromagnetic waves ( Figure 27 f). Wang et al [ 177 ] prepared a shielding material with a layered structure of conductive pearls. When an electromagnetic wave reached the surfaces of the conductive pearls, it would interact with the carrier wave on the surface of MXene and thus become partially reflected.…”

High-Performance Microwave Absorption Materials: Theory, Fabrication, and Functionalization

“…For radar stealth, MAMs are the core to absorb microwaves to achieve radar stealth. Toward infrared stealth, two main methods are always employed: one is to reduce the infrared emission rate of the target, − such as the method of attaching a layer of coating on the target; the other is to reduce the temperature of the target, such as the method of attaching a heat insulation layer on the target …”
