An environmentally friendly chitosan-derived VO2/carbon aerogel for radar infrared compatible stealth

Lightweight, Compressible, and Multifunctional Organic–Inorganic Nanofibrous Aerogels for Enhanced Microwave Absorption

“…In the process of electron transport, the uneven distribution at the heterogeneous interface leads to the macroscopic electric moment to promote interface polarization . Besides, the well-dispersed honeycomb-like carbon nanofiber skeleton provided continuous conductive pathways, which induced active migrating electrons and hopping electrons, leading to an intensive conductive loss . Moreover, the doping of S and N atoms supplied numerous defects, which could lead to the rearrangement of dipoles and serve as polarization centers in the alternating electric field, giving rise to dipolar polarization.…”

MoS2-Based Nanocomposites for Microwave Absorption: A Review

“…135 At present, stealth materials have been widely used in aircraft, main battle tanks, ships, arrows, and bombs. 136 For ground weapons, it is important to prevent attacks by airborne radar or infrared detection, radar-guided weapons, and laser-guided bombs. 137 Importantly, for combat aircraft, it is mainly to prevent the detection of airborne early warning aircraft radar, airborne fire control radar, and infrared equipment.…”

“…Stealth materials could not only reduce detection rate and improve their own survival rate but also increase aggression in order to obtain the most direct military benefits . At present, stealth materials have been widely used in aircraft, main battle tanks, ships, arrows, and bombs . For ground weapons, it is important to prevent attacks by airborne radar or infrared detection, radar-guided weapons, and laser-guided bombs .…”

Flexibly stretchable acrylic resin elastomer films for efficient electromagnetic shielding and photothermal conversion

“…With the advent of the 5G (fifth-generation communication technology) era and the rapid development of multi-functional as well as highly integrated electronic devices, electromagnetic radiation pollution has become an urgent problem that needs to be solved. 1–5 Electromagnetic interference (EMI) caused by electromagnetic waves will not only cause significant harm to human safety and health but also directly affect the regular operation of precision electronic equipment. In severe cases, it may lead to data loss, information leakage, and even irreversible damage to the equipment itself.…”
