Abstract

The invention provides a method for generating a polarized light with dynamic characteristics. The method comprises the following steps of: filling a graphene dispersion liquid into a glass box; and enabling a natural light to penetrate through the glass box filled with the graphene dispersion liquid, wherein the natural light penetrating through the glass box is converted into the polarized light with the dynamic characteristics; and the light intensity of the polarized light with the dynamic characteristics can be adjusted and controlled by adjusting the concentration of the graphene dispersion liquid, the thickness of the glass box as well as magnetic field intensity of a permanent magnet and an electromagnet. The polarized light with the dynamic characteristics, which are generated by using the method provided by the invention, can be used for preparing polaroids, polarized light modulators and a plurality of electronic devices.

Description

Technical field [0001] The invention belongs to the technical field of polarized light, and relates to a method for generating polarized light with dynamic characteristics by utilizing a graphene dispersion liquid. Background technique [0002] Polarized light has been widely used in life and instruments, such as: car lights, three-dimensional movies, liquid crystal displays, cameras, etc. There are mainly the following ways to obtain polarized light from natural light: reflection and refraction, birefringence, scattering, dichroic material absorption, wire grating or metal film. Different types of polarizers have their own characteristics, and the best application results can be obtained in different occasions. For example, metal type polarizers can be used in places with high temperature, and scattering polarizers require instruments that truly reflect the color of natural light. The birefringence type is more used in polarization instruments such as prisms. [0003] The...
