“…[4][5][6][7][8][9][10][11][12][13][14] In recent years, with the development of infrared detecting technologies, low infrared-emissivity materials have received considerable attention, particularly on their military applications, such as to camouflage military equipment or protect personnel and vehicles from infrared detection. 15 In the past decade, several kinds of materials, namely conductive polymeric material, nanostructure, ultrafine particle, strongly magnetic material, and semi-conductive material, have been thoroughly studied, in an attempt to achieve infrared stealth. However, these materials either have a high standard of emissivity or are complex in structure, [16][17][18][19][20][21] limiting their range of application to a relatively small field.…”
