Preparation and Thermoelectric Properties of TiS2/PEDOT:PSS Composite Films
The development of high-performance thermoelectric materials is the key to improve the thermoelectric conversion efficiency.Titanium disulfide(TiS2)is a two-dimensional thermoelectric material with excellent performance.In order to further improve its thermoelectric properties,titanium disulfide(TiS2)/Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)composite films with different structures were prepared.The thermoelectric properties of the composite film have been significantly improved,and its power factor can reach 368.58 μW·m-1·K-2.The preparation of TiS2/PEDOT:PSS composite film with sandwich structure is beneficial to obtain a more regular organic-inorganic heterogeneous interface,and then improve the thermoelectric properties of the composite film through the interface effect.
