Abstract

The invention discloses a copper-7, 7, 8, 8-tetracyanoquinodimethane material and a preparation method and an application thereof. The method comprises the following steps: in an inert atmosphere, dissolving -7, 7, 8, 8-tetracyanoquinodimethane in acetonitrile; and then, adding cuprous iodide, and carrying out a reaction under reflux to obtain the material. The material prepared by the invention can be used for preparing organic thermoelectric materials. Through verification, the thermoelectricity of the copper-7, 7, 8, 8-tetracyanoquinodimethane doped by 2, 3, 5, 6-tetrafloro-7, 7', 8, 8'-tetracyanodimethyl p-benzoquinone is remarkably improved, for instance, when the dosage concentration of 2, 3, 5, 6-tetrafloro-7, 7', 8, 8'-tetracyanodimethyl p-benzoquinone under 360K is 1mol%, the power factor is improved from 1.4 mu W / mK<2> to 2.2 mu W / mK<2>. Meanwhile, the preparation method provided by the invention is simple in process, easy in preparation and low in cost.

Description

technical field [0001] The invention relates to a metal-organic coordination polymer thermoelectric material, a preparation method and application thereof, and belongs to the technical field of organic thermoelectric materials. Background technique [0002] Thermoelectric materials use the thermoelectric effect, that is, the Seebeck effect, to realize the conversion between thermal energy and electrical energy. Thermoelectric materials are mainly used in thermoelectric power generation, electric refrigeration, and various sensor devices to recover various waste heat and convert them into electrical energy. The improvement of utilization efficiency alleviates the energy crisis; at the same time, refrigeration and heating devices made of thermoelectric materials using the Peltier effect also have broad application prospects because of their characteristics of no moving parts, no noise, and no pollution. [0003] At present, the research on thermoelectric materials mainly focus...
