Abstract

The invention relates to a preparation method of a silver telluride / fabric composite thermoelectric material. The silver telluride / fabric composite thermoelectric material is prepared by a gas phase induced reduction method for the first time. The preparation method comprises the steps of firstly, adding a proper amount of AgNO3, TeO2, mercaptopropionic acid, a surfactant and the like into a proper amount of deionized water, and uniformly stirring the chemicals until the chemicals are completely dissolved, thereby preparing an Ag2Te precursor solution; and soaking a fabric in the Ag2Te precursor solution for a period of time, then suspending the fabric in a beaker, adding a solution containing a reducing agent into the bottom of the beaker, placing the beaker on a heating table and heatingthe beaker to a certain temperature for gas phase reduction to generate the silver telluride / fabric composite thermoelectric material. The method has the advantages of simple process, convenient operation, large-scale production and the like. The prepared silver telluride / fabric composite thermoelectric material is excellent in thermoelectric performance and has a wide application prospect and ahigh market value in the fields of thermoelectric power generation and refrigeration devices.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric materials, and mainly relates to a preparation method of silver telluride / fabric composite thermoelectric materials. Background technique [0002] Since the beginning of the 21st century, the problems of environmental pollution and energy crisis have become increasingly serious, and there is an urgent need to research and develop environmentally friendly new energy materials. Thermoelectric materials are environmentally friendly functional materials that realize direct conversion between thermal energy and electrical energy through the transport of carriers (electrons or holes) inside solids. [0003] At present, most of the thermoelectric materials used in practice are inorganic thermoelectric materials (such as bismuth telluride-based alloys, lead telluride-based alloys, etc.), and the thermoelectric devices prepared by using the above-mentioned inorganic thermoelectric materials have dis...
