Title:
DISCOID LIQUID CRYSTAL MOLECULE FUNCTIONAL MODIFIER, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/082523
Kind Code:
A1
Abstract:
The present invention relates to a discoid liquid crystal molecule functional modifier, and a preparation method therefor and the use thereof. In the invention, a discoid liquid crystal molecule functional modifier is first synthesized by using a trimesoyl chloride monomer and a flexible carbon chain compound with an amino group as raw materials; and then the prepared discoid liquid crystal molecule functional modifier is mixed with a polymer matrix, and a composite film material with good performance is prepared by means of a tape casting method or a melt extrusion method. By using the discoid liquid crystal molecular functional modifier, the crystalline structure of a polymer is effectively adjusted and controlled, the grain size of the polymer is reduced, the content of a β-phase is increased, and the interface interaction between same and the polymer matrix is increased, such that the dielectric constant, the breakdown field strength, the mechanical properties and the energy storage density of a composite film material are improved. The present invention has the advantages of readily available raw materials, a simple synthesis method, an adjustable and controllable size, a high yield, a small amount, ease of purification, suitability for industrial production, etc., and has better application prospects from the aspect of adjusting and controlling the crystalline structure and the performance of a polymer film material.
