Problems solved by technology

[0003] For a long time, alloy thermoelectric materials with high ZT value have been widely used, such as Bi 2 Ti 3 , PbTe, etc.; however, alloy materials have problems such as toxicity, lack of raw materials, and poor thermochemical stability, which are not suitable for large-scale applications; in view of this, in recent years, oxide materials have begun to attract the attention and attention of thermoelectric materials researchers.
[0004] At present, people have carried out a lot of experimental research on oxide thermoelectric materials. Although various types of materials have been made, when they are attached and formed into films, they often show poor bonding strength with the substrate, which will affect the use. Stability and longevity, which reduces the competitiveness of the market

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a processing method of a high-stability nano superlattice electrothermal material. Background technique [0002] Fossil energy is currently the main source of energy, the energy crisis caused by its non-renewability and the greenhouse effect caused by the emission of carbon dioxide during use have attracted more and more attention. According to statistics, about two-thirds of the energy of fossil energy is wasted in the form of waste heat in use; if this part of waste heat can be recovered, it is obviously of great significance to alleviate the energy crisis and solve the greenhouse effect; in In this context, thermoelectric materials, as functional materials that can directly convert thermal energy and electrical energy, have received more and more attention in recent years. [0003] For a long time, alloy thermoelectric materials with high ZT value have...
