Historical research process of thermoelectric materials and their application in smart textiles
The research history of thermoelectric materials and their applications in smart textiles were reviewed.The future de-velopment direction of thermoelectric materials was analyzed.The development of thermoelectric materials can be divided into three generations:the first generation mainly consists of selenide and telluride based materials,which have high thermoelectric properties but may pose an environment hazard;the second generation is mainly based on oxide or silicide ceramic materials,which have lower costs and good environmental friendliness,but the thermoelectric conversion efficiency and mechanical strength need to be improved;and the third generation mainly involves composite materials of poly(3,4-ethylenedioxythiophene),carbon nanotubes and graphene,etc.,which have the advantages of light weight,good flexibility,high thermoelectric performance and multifunctionality,but the preparation has the disadvantages of complex process,high cost and poor stability.The application of thermoelectric materials in smart textiles involves the application of thermoelectric effect principles,the application of organic and inorganic thermoelectric materials and the improvement of carbon nanotube doping modification methods.The research direction for the future development of thermoelectric materials will be focused on developing low-cost and efficient preparation processes,optimizing material composition and structural design and improving the thermoelectric conversion efficiency of materials.
