The responsive photonic crystal Nano-chain is taken as a minimum color development unit (Nano light, 2020, volume 20, 803), the unique structural advantage of the responsive gel with Nano-scale is taken as a shell layer to wrap equidistant monodisperse magnetic particles into a 'pod' structure, which stands out in the traditional responsive photonic crystal sensor, and the Nano-scale responsive polymer shell layer can enable ions or other substances to diffuse quickly and reach swelling and shrinkage balance more quickly, so that quick response is realized (the flexible photonic Nano-chain with tunable photonic band gap, a preparation method thereof and application of CN 104629232A). According to the principle, functional photonic crystal materials such as a thermosensitive response type photonic crystal nano chain (a method CN110423305A for regulating and controlling the particle distance of Fe3O4@PVP@PNIPAM magnetic photonic crystal nano chain) and a glucose response type photonic crystal nano chain (a glucose response type photonic crystal sensor, a preparation method and a using method CN 110987820A) are prepared.
However, the currently developed responsive photonic crystal nano-chains can only be suspended and dispersed in a liquid, and a magnetic field needs to be continuously applied to enable the photonic nano-chains to maintain orientation so as to display color. In addition, the process of cleaning and redispersion is prone to loss, entanglement or breakage of the photonic nanochains when repeated use is required, resulting in deterioration of optical properties. Finally, the chain-shaped structure is suspended in the liquid and drifts along with the solution, so that the pollution of the sample is easily caused. The above-mentioned disadvantages limit their application in electrochromic, thermochromic, display device and sensing fields.
