Abstract

A quaternary ammonium salt ionic liquid crystal polymer with temperature-controlled electronic switch performance and its preparation method and application belong to the field of ionic liquid crystal materials. The quaternary ammonium salt ionic liquid crystal polymer with temperature-controlled electronic switch performance has a general structural formula: it is an ionic liquid crystal compound based on a polysiloxane main chain structure and containing imidazolium bromium salt groups and mesogens , composed of polymethylhydrosiloxane, allyl bromide, N-alkylimidazole and small molecular liquid crystals containing terminal ethylenic bonds. The ionic liquid crystal compound adjusts the glass transition temperature, electrical conductivity and liquid crystallinity by changing the chemical structure of the polymer, so as to realize its temperature-controlled electronic switch performance.
