Embodiment 1

[0025] The preparation process of multipolar axially plastic ferroelectric and piezoelectric materials containing trimethylchloroethylamine: mix 5mmol trimethylchloroethylammonium chloride with 10mL deionized water, and add 5mmol trichloride while stirring gallium. The mixed solution was stirred for 20 minutes, filtered to obtain a clear solution, volatile and grown at normal temperature and pressure, and colorless transparent crystals were obtained after standing for 3 to 7 days.

Embodiment 2

[0027] The preparation process of multipolar axially plastic ferroelectric and piezoelectric materials containing trimethylchloroethylamine: mix 5mmol trimethylchloroethylammonium chloride with 20mL of ethanol, and add 5mmol of gallium trichloride while stirring . The mixed solution was stirred for 50 min, filtered to obtain a clear solution, and volatilized and grown at normal temperature and pressure. After standing for 3 days, a colorless transparent crystal was obtained.

Embodiment 3

[0029] The preparation process of multipolar axially plastic ferroelectric and piezoelectric materials containing trimethylchloroethylamine: mix 5mmol trimethylchloroethylammonium chloride with 15mL of deionized water, and add 6mmol trichlorohydrin while stirring gallium chloride. The mixed solution was stirred for 60 min, filtered to obtain a clear solution, volatile and grown at normal temperature and pressure, and colorless transparent crystals were obtained after standing for 1 day.

Abstract

The invention discloses a trimethylchloroethylamine-containing multipolar axis plastic ferroelectric and piezoelectric material as well as preparation and application thereof, which relates to ferroelectric and piezoelectric materials. The chemical formula of the trimethylchloroethylamine-containingmultipolar axis plastic ferroelectric and piezoelectric material is [(CH3)3NCH2Cl]GaCl4. The preparation method comprises the following steps of mixing trimethylchloroethyl ammonium chloride with a solvent, then adding gallium trichloride, stirring, volatilizing and growing a clear solution obtained by filtering, and standing to obtain the trimethylchloroethylamine-containing multipolar axis plastic ferroelectric and piezoelectric material, namely [(CH3)3NCH2Cl]GaCl4. A polycrystalline tabletting sample of the obtained multipolar axis plastic ferroelectric and piezoelectric material at room temperature has excellent piezoelectric property. The trimethylchloroethylamine-containing multipolar axis plastic ferroelectric and piezoelectric material can be applied to preparation of ferroelectric storage materials, signal sensing materials, energy collection materials and the like.

Description

technical field [0001] The invention relates to molecular-based ferroelectric and piezoelectric materials, in particular to multipolar axis plastic ferroelectric and piezoelectric materials containing trimethylchloroethylamine and its preparation and application. Background technique [0002] Ferroelectric materials are a class of polar functional materials that have spontaneous polarization and the polarization can be reversed under the action of an applied electric field (Lines, M.E.; Glass, A.M.; Burns, G. Principles and Applications of Ferroelectrics and Related Materials[J] . Phys. Today 1978, 31, 56.). At the same time, due to the existence of polarity, ferroelectric materials all have piezoelectric properties and have the characteristics of piezoelectric materials. In recent years, molecular-based ferroelectric and piezoelectric materials, as flexible, easy to prepare, easy to process, rich in structure and easy to modify, are expected to make up for the disadvantage...
