不同涤纶织物基底对光子晶体结构的构建及其生色效果的影响

s the basic structural units, monodispersed P (St- MAA) colloidal microspheres are self-assembled to construct photonic crystal structure on different types of polyester fabrics via gravity sedimentation method. The effects of the tightness and smoothness of polyester fabrics on the structural colors of P (St-MAA) photonic crystals and their possible mechanism are investigated. Field emission scanning electron microscopy (FESEM), three-dimensional video microscopy and Digieye digital imaging system are used to characterize the surface morphologies of polyester fabrics before and after self-assembly, structural colors and their reflectance spectra. The results show that P (St-MAA) colloidal microspheres are easier to fill voids between fibers and yarns of smooth polyester fabrics with relatively tight textural structure during the gravity sedimentation self-assembly process, thus the well-ordered photonic crystal structures can be easier obtained and present bright structural colors. In particular, the preferable self-assembled effect can be accomplished in tight plain woven fabrics with the similar warp yarn and filling yarn.
