Abstract

The invention relates to an adjustable three-dimensional chiral structure and a preparation method thereof, and mainly relates to the field of optical chiral structures. The three-dimensional chiral structure comprises conductive glass, grating layers, a plurality of polystyrene spheres, a chiral structure layer, a first colloid and a second colloid. Deformation characteristics of a plurality of polystyrene spheres are utilized; when the chirality of the three-dimensional chiral structure needs to be adjusted, the first colloid and the second colloid are extruded by using opposite force, and aplurality of polystyrene spheres are enabled to form. The grating layers are arranged on the two sides of the polystyrene spheres, the heights of the polystyrene spheres can be changed under the action of pressure, then the local height difference and period of the chiral structure units in the chiral structure layer can be changed, and the purpose of adjusting three-dimensional chiral structureparameters is achieved.

Description

technical field [0001] The invention relates to the field of optical chiral structures, and mainly relates to an adjustable three-dimensional chiral structure and a preparation method thereof. Background technique [0002] Chiral structure plays an important role in life, and chiral structure refers to the property that it cannot overlap with the mirror image. [0003] In the prior art, the chiral structure is generally adjusted by re-preparing a new structure, or by adding some temperature-sensitive materials to the structure, and adjusting the temperature to adjust the parameters of the structure. [0004] However, it takes more time to prepare the structure again, which is not only time-consuming and laborious, but also wastes more resources. Regulating structural parameters through temperature will also cause inaccurate temperature regulation due to the influence of the surrounding environment, the regulation range is small, and the temperature regulation device is rela...
