摘要：

The infrared stealth fabric was prepared using W-doped VO2 (M) paints by the coating technology. The thermochromic W-doped VO2 (M) was synthesized through hydrolysis method and two-step calcinations under N-2 atmosphere. The powders were evaluated by scanning electron microscopy, X-ray diffraction patterns and differential scanning calorimetry. The infrared emissivity of coated cotton fabric was measured by IR-2 Infrared Emissometer, which was as low as 0.752. The low infrared radiation intensity for coated cotton fabric was detected using the infrared imaging systems above the phase temperature of W-doped VO2 (M). The results indicated that the W-doped VO2 (M) thin films exhibited thermal infrared stealth performance, which could adapt to the surroundings spontaneously. (C) 2014 Elsevier B. V.
