Recent advances in electrochromic materials and devices for camouflage applications

Abstract

Electrochromic (EC) materials and devices, whose optical properties (color, reflectance, emittance, etc.) can be manipulated by switching a low-voltage bias, show great promise in many applications such as smart windows,...

Wearable electrochromic materials and devices: from visible to infrared modulation

“…EC camouflage is based on the electrochemically driven redox process of EC materials to produce colour/reflectivity/emissivity changes so that the objects exhibit adaptive changes to the surrounding environment and achieve perfect concealment from visual and infrared detection. 138 The ideal EC camouflage devices require smaller chromatic aberration with the surrounding environment to ensure camouflage concealment, better flexibility to ensure comfort and practicality, and better stability and durability to support their life.…”

Design Strategies for High Reflectivity Contrast and Stability Adaptive Camouflage Electrochromic Supercapacitors

“…The performance of ECSCs was closely related to the charge transfer and ion transfer process at the interface between electrode and electrolyte. 35,36 The EIS of two ECSCs is shown in Figure 7f. The steeper slope in the high-frequency region of ECSCs2 than that of ECSCs1 reflects the excellent energy storage behavior of ECSCs2.…”

Colorful variation of tetraphenylethene derivatives in the solid state

“…1 Among them, the variation of fluorescence properties and appearance color upon external stimuli is the most commonly used feature for the advantage of easy detection and low cost. According to external stimuli including light, temperature, force, electricity, magnet, and so on, stimuliresponsive chromic materials can be divided into the corresponding categories as follows: photochromism, [9][10][11][12] thermochromism, [13][14][15] mechanochromsim, [16][17][18][19][20][21][22][23][24][25][26] electrochromism, [27][28][29][30] and magnetochromism. 31,32 These stimuli-responsive chromic materials have exhibited a wide range of promising applications in chemosensors, [33][34][35][36] biosensors, [37][38][39] photoelectric devices, [40][41][42] displays, [43][44][45] anti-counterfeiting, 46,47 etc.…”
