The thermoelectric properties of telluride nanorods coated with Te-PEDOT:PSS were enhanced by the addition of a small amount of nanocarbon material such as graphene nanoparticles or small bundled single-walled carbon nanotubes. In order to apply the nanocarbon composite material to the printing process, soluble Te-PEDOT:PSS was mixed with a small amount of nanocarbon without degrading the thermoelectric performances. The thermoelectric properties of the Te-PEDOT:PSS nanocomposites were greatly improved, especially when a rather small amount of SSWNTs was added to Te-PEDOT:PSS owing to the structural and electrical properties of the SSNWTs. The fabricated thermoelectric generator with SSWNT-mixed Te-PEDOT:PSS by spray printing showed output power of 126 nW, which is 18 times higher than that of GNP-mixed Te-PEDOT:PSS. |
