Abstract

The invention discloses a preparation method of carbon black doped liquid crystal microcapsules, and belongs to the technical fields of fine chemical engineering and material science. The carbon blackdoped liquid crystal microcapsule is characterized in that a liquid crystal is doped with modified carbon black which exists in the microcapsules for absorbing transmitted visible light, so that thetransmitted light penetrating through the liquid crystal is reduced, human eyes mainly see selectively-reflected light of the liquid crystal, and liquid crystal microcapsules are more remarkable in color. The method is easy to operate, and is environmentally friendly. The liquid crystal microcapsules prepared by the method are remarkably improved in brightness, can present remarkable color under naked eyes, and can be widely applied in the fields of body temperature precise measurement, liquid crystal displays, electronic paper, liquid crystal lasers, anti-counterfeit packages and smart textile.

Description

Technical field

[0001] The invention belongs to the technical field of fine chemicals and materials science, and specifically relates to a method for carbon black doped liquid crystal microcapsules. Background technique

[0002] Cholesteric liquid crystal is a temperature-responsive reversible color material. It has the advantages of fast response speed, high color change sensitivity, rich color change levels, and good light resistance stability. Therefore, it is widely used in precision temperature measurement, liquid crystal display, electronic paper, LCD lasers, anti-counterfeiting packaging, smart textiles and other fields. In order to stabilize and protect the cholesteric liquid crystal, it is usually microencapsulated.

[0003] Cholesteric liquid crystal has no chromophore group, it has a spiral structure in the spatial structure. The liquid crystal structure obtained by combining nematic liquid crystal and chiral additives is similar to cholesteric liquid crystal, and it is...
