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
Affiliated technical field
The invention belongs to the polarized-light technique field, relate to and utilize the generation of Graphene dispersion liquid to have the method for behavioral characteristics polarized light.
Background technology
Polarized light has been used widely at aspects such as life, instruments, as: automobile lamp, three-dimensional film, LCDs, camera etc.Obtain the polarized light mode from natural light and mainly contain following several kinds: reflection and refraction, birefringence, scattering, dichroism material absorbing, tinsel grating or metallic film.The variety classes polaroid has the characteristics of himself; Can obtain best effect under the different occasions; Can be used for the higher occasion of temperature like the metal types polaroid; Scatter-type polarizing disc requires on the instrument of true reflection natural light color, reflect, the birefringence type then more application in polarimeter devices such as prisms.
The reflex of nonmetallic surfaces such as the air molecule in the atmosphere, the scattering process of particulate and cloud layer, the face of land; The a large amount of polarized lights that produce are because the polarized light that the scattering process of air molecule, particulate and cloud layer produce has behavioral characteristics usually.Lot of documents shows: many animals can obtain more useful navigation information according to the dynamic attribute of sky polarized light, and utilize sky polarized light dynamic perfromance to navigate.Also there be not at present to produce polaroid or device with behavioral characteristics polarized light.[Rossel?S，Wehner?R，Polarization?vision?in?bees.Nature，1986，323(6084)：128-131.Brunner?D，Labhart?T，Behavioural?evidence?for?polarization?vision?in?crickets.Physiol?Entomol，1987，12(1)：1-10.Dacke?M，Nilsson?D?E，Scholtz?C?H，et?al.Animal?behavior：insect?orientation?to?polarized?moonlight.Nature，2003，424(6944)：33.Muheim?R，Phillips?J?B，
