Abstract

The invention relates to a hydrophobic photon crystal-structure color-producing material and a preparation method thereof, belonging to the field of new material preparation. The hydrophobic photon crystal-structure color-producing material is composed of a matrix, a photon crystal layer positioned on the matrix and a cationic surfactant layer attached to the surface of the photon crystal layer, wherein the photon crystal layer is formed by filling an adhesive in the gaps of microspheres which are arranged periodically and closely; and the microspheres are selected from polystyrene, polymethyl methacrylate, silicon dioxide, titanium dioxide or zirconium dioxide microspheres. The hydrophobic photon crystal-structure color-producing material has the advantages of high hydrophobicity and high strength, is suitable for coloring glass, silicon chips, steel straps, copper sheets, aluminum sheets, cotton fabrics, silk, plastic films or paper, and has wide application prospects.

Description

technical field [0001] The invention relates to a hydrophobic high-intensity photonic crystal structure chromogenic material and a preparation method thereof, belonging to the field of new material preparation. Background technique [0002] Color can be divided into two categories according to the source, one is pigment-generated color, that is, chemical color; the other is structural color produced by the interaction of light and microstructure, which is a new direction of color chemistry today (Liu F, Dong B Q , Liu X H. Optics Express, 2009, 17(18): 16183-16191). Among various structural chromogenic pathways, the ordered structure of alternating high and low refractive index materials assembled by nano-micro-scale microspheres has the function of regulating photon transmission and is one of the effective ways for structural chromogenicity (Rudisill S G , Wang Z Y, Stein A, Langmuir, 2012, 28(19): 7310-7324; Chuang V P, Gwyther J, Mickiewicz R A, Nano Letter, 2009, 9(12):...
