    Abstract:

    A novel bionic camouflage material, which is constituted of transparent poly(vinyl chloride) surface, chlorophyll/poly(vinyl alcohol) film, high-vapor-barrier water bag and paper, was designed and prepared by simulating plant leaves. The transparent poly(vinyl chloride) surface was used to provide waterproof capability of the camouflage material; the chlorophyll was concealed into the high-oxygen-barrier poly(vinyl alcohol) film to improve its photostability; the water was sealed into the bag of high-vapor-barrier poly(vinylidene chloride) to prevent its vaporization loss; and the paper was used to simulate the spongy mesophyll of plant leaf organs. The result of spectral tests showed that the reflectance spectra of camouflage material and plant leaves, whose similarity was 0.9983, exhibited the same characteristics in visible, near infrared and short wave infrared wave bands, and the spectral characteristics of camouflage material did not change after three months’ sunlight treatment. The bionic camouflage material, which displayed a high spectral similarity with plant leaves and a good weather resistance, is an effective method to take on reconnaissance of hyperspectral imaging hopefully.
