Abstract:Abstract: This paper aims to prepare a device that can quickly display the color pattern matching with the environment, so as to achieve the purpose of adaptive environment. Taking N,N-Dimethyldodecylamine oxide (C12DMHO) as the basic unit, the PNIPAM-co-PDAAM-co-PAM cross-linking network was formed under the condition of UV polymerization of N- isopropylacrylamide (NIPAM), diacetone acrylamide (DMAA) and acrylamide (AM), and a fast responsive C12DMHO/PNIPAM-co-PDAAM-co-PAM temperature sensitive photonic crystal hydrogel was prepared. After coating, it is combined with the integrated electric heating plate to construct an adaptive structural color device. Through the reverse color spectrum test and infrared imaging test, it is concluded that the response temperature of the material can be adjusted in the range of 0 ~ 80 ℃ by adjusting the proportion of the above polymerizable monomers NIPAM, DMAA and am. When the monomer content in the material is PNIPAM 0.2 g, DMAA 0.2 g, am 0.05 g and MBAA 50 mg, the response temperature range is 24-30 ℃, and the structural color can change rapidly, dynamically and reversibly in the visible light region.
