摘要
为满足现代战争对军用设备视觉隐身的需求,设计了一种具有环境自适应性,制备涂装简单,制作过程绿色环保的光子晶体温敏变色材料。采用乳液聚合法制备粒径分别为132 nm、205 nm、275 nm、300 nm的聚苯乙烯微球,并将其垂直沉降自组装形成结构高度有序、结构色明显的三维聚合物光子晶体。对温度敏感的聚N-异丙基丙烯酰胺/丙烯酰胺水凝胶与聚苯乙烯三维光子晶体相结合,制备出结构色随环境温度发生改变的光子晶体凝胶膜。基于色度、饱和度、亮度色彩模式,通过实验分析验证了该材料颜色可随环境温度变化做出响应。结果表明,光子晶体温敏变色材料可以实现环境温度自适应响应,在视觉伪装方面具有一定的应用前景。
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.
