Abstract
The invention relates to a polymer/nanocrystal hybrid light guide plate and a preparation method thereof, and belongs to the technical field of light guide plates. The nanocrystal modified by the polymerizable surfactant is copolymerized with a polymer monomer to prepare the light guide plate with the uniformly dispersed nanocrystal inside, and the nanocrystal and the polymer have a bonding effect. The scattering behavior of the nanocrystals uniformly distributed in the polymer/nanocrystal light guide plate on the light meets the Rayleigh scattering law, and finally the polymer/nanocrystal hybrid light guide plate has excellent emergent brightness and uniformity. The polymer/nanocrystal hybrid light guide plate can realize double-sided light guide and random cutting. The brightness and uniformity of emergent light can be adjusted by adjusting the concentration of the nanocrystals in the polymer matrix according to the required size. And the light guide plate is directly formed after the polymer monomer injected into the mold is copolymerized with the nanocrystal modified by the polymerizable surfactant, subsequent processing and treatment are not needed, and the light guide plate is simple and convenient to manufacture.

Technical Field
The invention belongs to the technical field of light guide plates, and particularly relates to a polymer/nanocrystal hybrid light guide plate and a preparation method thereof.
Background
The light guide plate can convert point light sources and line light sources into surface light sources. In order to increase the light-emitting efficiency and uniformity of the light guide plate, light guide dots are usually introduced into the bottom of the light guide plate to improve the performance of the light guide plate, or the light guide plate is made into a wedge shape. However, the current processes for preparing the light guide plate mainly include printing, laser engraving, chemical etching, direct injection molding and the like, and these methods usually require complicated professional equipment or precise secondary processes, which greatly increases the production cost and reduces the production efficiency. In addition, the prepared light guide plate has application defects, such as incapability of being cut at will, single-sided light guide and the like, and is difficult to meet the market demand, and the structure and the process of the light guide plate still need to be further improved.

Note: the effect display degree is sequentially from good to bad: excellent +, excellent, good and poor
As can be seen from table 1, the light guide plates prepared according to examples 1 to 5 of the present invention have nanocrystals uniformly distributed therein to efficiently convert the linear light source into the surface light source, and exhibit good uniformity. The excellent brightness and uniformity of the light output of the polymer/nanocrystal light guide plate are benefited by the fact that the scattering behavior of light by single nanocrystals in the polymer matrix inside the light guide plate satisfies the rayleigh scattering law. The prepared polymer/nanocrystal hybrid light guide plate with the thickness of 0.5-10 mm can realize double-sided light guide and random cutting. And the light guide plate is directly formed after the polymer monomer injected into the mold is copolymerized with the nanocrystal modified by the polymerizable surfactant without subsequent processing and treatment. The brightness and uniformity of emergent light can be adjusted by adjusting the concentration of the nanocrystal in the polymer matrix according to the required size.
