Micro-fluidic film for visible and infrared dual-band camouflage and preparation method of micro-fluidic film

The invention belongs to the technical field of camouflage, and relates to a micro-fluidic film for optical camouflage and a method, in particular to a micro-fluidic film for visible and infrared dual-band camouflage and a preparation method thereof.The micro-fluidic film is of a single-layer or multi-layer micro-channel structure, the back face of the micro-fluidic film is a reflection layer, and the back face of the micro-fluidic film is a reflection layer. Microfluid is introduced into the microchannels, and the overall visible color and infrared emissivity of the microfluidic film are controlled through the microfluid in each layer of microchannel. The infrared emissivity and color of the micro-fluidic film for visible and infrared dual-band camouflage are changed by controlling the micro-fluid, and the micro-fluidic film has the advantages of initiative, controllability and accurate control. When the color and temperature of the background where the target object is located change, the color and emissivi
