Abstract

The invention discloses a thiocyanate cobalt hydrogen bond type ferroelectric material as well as a preparation method and application thereof. In the present invention, dabco is fully dissolved in methanol, then hydrochloric acid with a mass concentration of 36% to 37% is added dropwise and fully stirred to obtain solvent 1; cobalt chloride is added to water and fully dissolved to obtain solvent 2; potassium thiocyanate Add it into water to fully dissolve to obtain solvent 3; mix solvent 2 and solvent 3 and add it to solvent 1, and mix well to obtain a mixed solvent. The molar ratio of cobalt chloride, potassium thiocyanate, and dabco in the mixed solvent is 1 ~2:5~6:1~2; the mixed solvent is placed in a clean environment for 6~8 days, and the precipitated dark blue massive crystals are thiocyanate cobalt hydrogen bond type ferroelectric materials. The material structure of the present invention is easy to control, has excellent electrical properties, and can be widely used in fields such as ferroelectric memory and infrared detectors; in addition, the preparation method of the present invention has the advantages of less energy consumption, low cost, and easy production, and is environmentally friendly .
