本发明公开种形貌可演变的无机-有机复合反蛋白石结构光子晶体的制备方法及应用。所述方法采用竖直沉积法制备有序性良好的光子晶体模板，并在其间隙中填充前驱体，通过在有机溶剂中去除光子晶体模板，制备得到反蛋白石结构光子晶体。本发明还通过电浸润过程，利用电压控制，实现了液滴在结构表面发生各向异性浸润，完成了反蛋白石光子晶体结构内部的形貌变化，并且使得浸润的地方发生颜色的变化。本发明利用该过程实现了光子晶体图案的快速、简单的制备方法，发展了光子晶体在图案化制备方面的又新方法，拓宽了光子晶体在光学器件、显示器、微流控设备等方面的潜在应用前景。 The invention discloses a preparation method and use of a morphology-variable inorganic-organic composite inverse opal structure photonic crystal. According to the preparation method, a photonic crystal template which has good sequentiality and is prepared through a vertical sedimentation method is used, gaps of the photonic crystal template are filled with a precursor and the photonic crystal template is removed through an organic solvent so that the morphology-variable inorganic-organic composite inverse opal structure photonic crystals are obtained. Through an electro-wetting process, under the control of voltage, anisotropic infiltration on the surface of the liquid drop structure is realized, morphology change in the inverse opal structure p
