本项目涉及聚丁二炔反蛋白石结构光子晶体的制备及其多重响应性能研究，以蛋白石型光子晶体为模板，将丁二炔溶胶填充到其缝隙中，采用牺牲模板法制备聚丁二炔反蛋白石结构光子晶体。主要研究内容如下：（1）不同填充方法和溶胶浓度对光子晶体结构的影响；（2）分别通过光、热、离子等诱导使聚丁二炔结构发生转变，从而改变光子晶体的折射率，实现对光子晶体光子禁带的多重调控；（3）研究聚丁二炔反蛋白石大孔结构对外界刺激响应速率的影响，为制备高效多响应光子晶体提供新的思路和途径。

In this project, we demonstrate the fabrication of multiresponsive polydiacetylene inverse opal photonic crystals. The inverse opal photonic crystals are prepared based on sacrificial template method using poly(styrene-methyl methacrylate-acrylic acid) (P(St-MMA-AA)) as a template and 10,12-pentacosadiynoic acid as the conjugated diacetylene precursor infiltrated in the voids of opal template. Our researches will focus on the following aspects: first, the influence of different fill method and sol concentration on the structure of inverse opal is detailed studied; second, the phase change of polydiacetylene is in response to light, heat and ion, etc. The phase change results in the variation of refractive index. Thus, the manipulation of the stopband of inverse opal by light, temperature and ion can be achieved; finally,the impact of macropore structure of inverse opal on the response level will be also investigated. It will provide a novel strategy in fabricating multiresponsive photonic crystals with high response level.
