摘要： Disclosed are a polymer-stabilized liquid crystal composition and the use thereof. The composition comprises one or two polymerizable compounds represented by general formula I: (I), and further comprises a negative dielectric anisotropy liquid crystal composition, wherein the negative dielectric anisotropy liquid crystal composition has a dielectric anisotropy of Δε≤−1.5; and the added amount of the polymerizable compound(s) represented by general formula I is 0.1-0.5% of the total mass of the negative dielectric anisotropy liquid crystal composition. A polymer film formed after the polymerization of the provided liquid crystal composition containing the polymerizable compound(s) has a very good uniformity, such that the problem of liquid crystal displays having poor display can be improved. Moreover, an alignment film formed after the polymerization of the polymerizable liquid crystal composition has an excellent alignment force, and can improve residual image problems caused by an insufficient alignment force in a PSVA liquid crystal display. The provided liquid crystal composition containing the polymerizable compound(s) can realize an adjustable response speed, and can in turn meet the requirements of different technical process conditions.

摘要： There are provided a compound having a thermotropic liquid crystalline structure and a polyethylene glycol polymer. The compound is obtained by modifying an epoxide functional group in a thermotropic liquid crystalline molecule. The polyethylene glycol polymer is obtained by ring-opening polymerization thereof. The polyethylene glycol main chain polymer is easy to form in thin film, bulk, or fiber form, and has a high thermal conductivity and thus can be used alone or in the form of a composite material as a heat-dissipating polymer.
