The multi-layer graphene layer, the first lead wire, the power supply, the second lead wire and the conductive fabric layer are connected to form a loop. The voltage range of the power supply is 0-10 V. USE - The graphene self-adaptive infrared stealth fabric is useful in photoelectric invisible body (claimed) for improving infrared stealth of soldiers and weapon systems on battlefield. ADVANTAGE - The graphene self-adaptive infrared stealth fabric can be distributed based on the infrared radiation of the external environment, transfers the ionic liquid to the layer gap of the multi-layer graphene layer by adjusting the power supply voltage, controls infrared emission rate of the multi-layer graphene between 0.3-0.8 and infrared wavelength at 2-25 µm, changes the infrared radiation distribution state of graphene self-adaptive infrared stealth fabric to coordinate with the infrared radiation distribution state of the external environment, reduces the infrared radiation in contrast with the external environment to make the graphene self-adaptive infrared stealth fabric infrared image a part of the whole background infrared radiation image, achieves infrared stealth function of the fabric in real time, and has improved infrared shielding performance.
