Abstract

The invention discloses an organic bionic material and a preparation method. The organic bionic material is prepared from the following components in parts by weight: 1 to 8 parts of polyvinyl alcohol, 1 to 7 parts of metal chloride, 2 to 6 parts of colouring agent, 2 to 9 parts of cross-linking agent, and 5 to 6 parts of catalyst. The organic bionic material can simultaneously simulate plant leaf transpiration and a spectral reflection characteristic, and can simulate plant appearance, spectral reflection so as to achieve the aims of infrared, spectral imaging camouflage and woodland background visual camouflage.

Description

technical field [0001] The invention belongs to the technical field of infrared, spectral imaging camouflage and forest background visible light, and in particular relates to an organic bionic material and a preparation method thereof. Background technique [0002] Camouflage is taking steps to conceal oneself and confuse the enemy. The essence of camouflage is to simulate natural characteristics, eliminate or reduce the difference between the target and the environment background and between the real and false targets, and ensure the integration with the natural state. Infrared camouflage is the use of shielding, low-emissivity paint, thermal suppression and other measures to reduce or change the infrared radiation characteristics of the target to achieve low detectability of the target. However, tests have shown that the infrared emissivity control technology used in conventional infrared camouflage coatings and materials cannot guarantee all-day camouflage. Due to their...
