Preparation and properties of PEDOT:PSS/Te nanorod composite films for flexible thermoelectric power generator

Flexible Thermoelectric Materials and Generators: Challenges and Innovations

“…The crystal structure of Te is hexagonal and the bonds between adjacent atoms on the same chain are covalent, whereas the interactions between chains are thought to be a mixture of electrical and van der Waals forces . The π–π interactions in PEDOT:PSS tend toward a solid adhesive interface facilitated by the van der Waals forces in Te, so that the PEDOT:PSS is firmly coated on the surface of the Te nanorods . As a result, a highly conductive interface can be formed in between the PEDOT:PSS and the Te nanorods, leading to a high S 2 σ of 70.9 µW m −1 K −2 and a promising peak zT of ≈0.1 at room temperature .…”

One‐step Synthesis and Enhanced Thermoelectric Properties of Polymer–Quantum Dot Composite Films

“…Nowaone-step synthesis can be used to fabricate high-quality small-sized anions codoped poly (3,4ethylenedioxythiophene):dodecylbenzenesulfonate/Cl-tellurium (PEDOT:DBSA/Cl-Te) composite films using aseries of novel Te IV -based oxidants.T he synchronized production of PEDOTa nd Te results in thick and homogeneous films containing evenly distributed and well-protected Te quantum dots.Owing to the heavily doped crystalline polymer matrix as well as the < 5nmunoxidized Te quantum dot loading, at low Te concentrations as 2.1-5.8 wt %, the films exhibits high power factors of about 100 mWm À1 K À2 ,w hichi s5 0% higher compared to apure PEDOT:DBSA film.Thermoelectric (TE) materials,w hich can make direct conversion between heat and electricity,a re used in waste heat harvesting and refrigerating.T he performance of TE materials are determined by ZT (S 2 sT/k)o rp ower factor (S 2 s), where S, s, T,a nd k are the Seebeck coefficient, electrical conductivity,a bsolute temperature,a nd thermal conductivity,r espectively.C onducting polymers (CPs) especially poly(3,4-ethylenedioxythiophene) (PEDOT) have drawn great attention because of their relatively high s,l ow k,g ood flexibility,a nd cheapness.H owever,C Ps often possesses limited S 2 s mainly because to their low S value. Combining CPs with inorganic nanoparticles (INPs) has become an attractive route to achieve higher S and S 2 s while maintaining good flexibility and workability of apolymer.For example,P EDOT-based nanocomposites containing Te, [1][2][3][4][5] Te -based heterostructures, [6,7] PbTe, [8] Bi 2 Te 3 , [9][10][11][12] Sb 2 Te 3 , [13] Bi 2 S 3 , [14] WS 2 , [15] MoS 2 , [16] MoSe 2 , [17] SnS, [18] Ca 3 Co 4 O 9 , [19] GeO 2 , [20] Au, [21,22] and various kinds of carbon materials [23][24][25][26][27] were reported previously and exhibited S 2 s ranging from 0.1-237 mWm À1 K À2 .H owever,p roducing high-quality polymer dominant nanocomposites with less than 50 wt %i norganic Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.…”
