Abstract

The invention relates to a side-chain type liquid crystal polymer liquid crystal physical gel material and a preparation method thereof. The material contains the following components in percentages by mass: 90.0-99.0% of a liquid crystal material and 1.0-10.0% of a side-chain type liquid crystal polymer. By taking a small molecular liquid crystal as a working substance and the side-chain type liquid crystal polymer as a supporting material, the prepared liquid crystal physical gel material is high in modulus (the energy storage modulus can reach 104Pa above), good in thermal stability (the sol-gel transition temperature exceeds 190 DEG C) and high in small molecular liquid crystal content, and meanwhile, can adjust the chemical structure of the side-chain type liquid crystal polymer to regulate the sol-gel phase transition temperature of the liquid crystal physical gel so as to meet the using demand of different conditions.

Description

technical field

[0001] The invention relates to a liquid crystal physical gel material and a preparation method thereof, in particular to a side chain type liquid crystal polymer high modulus liquid crystal physical gel material and a preparation method thereof. Background technique

[0002] Liquid crystal is a kind of ordered fluid, which has the fluidity of liquid and the order of crystal at the same time. The unique properties of liquid crystals make them widely used in the electronics industry. Due to the advantages of low power consumption, low driving voltage, and high contrast, liquid crystal displays stand out among many display materials and become one of the most popular display materials in the market. Fluidity is an important attribute of liquid crystals, which enables liquid crystals to respond quickly under the action of an external field, but this also brings many problems to the development of large-scale liquid crystal devices, such as poor mechanical prope...
