The purpose of this study was to research the thermoelectric properties of PAT nanofiber and to fabricate the flexible thermoelectric module of PAT nanofiber.The PAT nanofiber mat and composite film of PAT nanofiber embedded in a conventional polymer was prepared, and the Seebeck coefficient and conductivity was evaluated. These materials showed a significant thermopower effect, and the nanofiber tended to have higher efficiency than non-nanofiber pristine films. But, this advantage was ascribed to be higher conductivity, and a narrow-line effect cannot be observed.A flexible thermoelectric module of PAT nanofiber packed in a laminated film with electrodes was made. This sheet module also had a significant thermopower effect.
