The Controllable Preparation And Thermoelectric Characterization Of Pedot Micro-nanospheres

In the past decades, as a new type of thermoelectric materials，conducting-polymerthermoelectric materials have attracted intense interests. Conducting-polymerthermoelectric materials have many advantages compared with ordinary materials, notonly have easy processing, corrosion-resistant，but also have special optical properties,good biocompatibility. So their applications are very extensive. Poly(3,4-ethylenedioxythiophene)(PEDOT) because of its high light transmittance, highconductivity, excellent thermal stability, have been widespread attention. Comparedwith bulk conducting-polymer, conducting-polymer nanostructures are applied insensors, actuators, solar cell and electrochromic because of the properties are causedby their nanoscaled size: optical, electrical, magnetic and other properties. In this paper，our research focuses on a efficient，facile，and highly controllable synthesis method ofconducting-polymer nanostructures. In addition, the thermoelectric properties of theconducting-polymer nanostructures are discussed.(1) The four size (50nm,100nm,500nm,1μm) PS latex were prepared byemulsion polymerization and microsuspension polymerization as the hard-template.Characterize nanostructures of the products and extracted by tetrahydrofuran.(2) PS/PEDOT core-shell composites based on the suspended PS particles as thehard-template, which were coated with PEDOT by in situ deposition polymerization.Explore the polymerization temperature, initiator types, doping ionic and otherconditions affected its structure and characterized. Finally, the hollow spheres ofPEDOT was prepared by dissolved the PS particles.(3) PEDOT composites with different sizes and structures, and thus itsThermoelectric properties were characterized by the electrical conductivity, thermalconductivity, coefficient Seebeck test.
