Abstract
A camouflage material with environmental adaptability, simple preparation and painting, and green production process was designed to meet the visual stealth requirements of military equipment. The polystyrene microspheres with diameters of 132 nm, 205 nm, 275 nm and 300 nm were prepared by using emulsion polymerization. Three-dimensional photonic crystals with highly ordered structure and obvious structural color were prepared by using vertical sedimentation self-assembly method. The temperature-sensitive PNIPAM/AM hydrogel and polystyrene three-dimensional photonic crystal were used to prepare a photonic crystal gel film with structural color changing with ambient temperature. Based on the analysis of HSB (hues, saturation, brightness) color model, it is verified that the color of the material can respond with the change of environment temperature. The results show that the thermochromic photonic crystal material can achieve adaptive response to ambient temperature and has certain application prospects in visual stealth.
