Abstract

Abstract: High power factor n-type organic thermoelectric nanocomposites are assembled by alternately depositing double walled-nanotubes (DWNT), stabilized by polyethyleneimine (PEI), and graphene stabilized by polyvinylpyrrolidone (PVP), from water using the layer-by-layer (LbL) assembly technique. This unique combination of carbon nanomaterials exhibits an electrical conductivity of 300 S cm −1 and a relatively stable power factor of 190 μW m −1 K −2 at room temperature. Graphical abstract: Highlights: Thermoelectric properties of n-type organic nanocomposites are characterized. An DWNT and graphene-based thin film has PF of 190 μW m −1 K −2 and is quite air-stable. A DWNT/graphene multilayer nanocomposite thin film has conductivity of 300 S/cm.
