Abstract:
Flexible thermoelectric (TE) fabrics were prepared by dip coating of a mixture solution of water base colloidal geraphen nano sheet(GNS) and carbon nano tube(CNT) and polyaniline (PANI) on polyester fabric. The phase composition and morphology of the TE fabrics were investigated by FTIR-ATR diﬀraction and feld emission scanning electron microscopy. The TE properties of the PANI/GNS or CNT coated fabrics with diﬀerent GNS and CNT loadings were measured in the temperature range from 303 to 338 K. As the content of GNS increased from 0.5 to 10 wt% and CNT increased from 0.5 to 20 wt%, the electrical conductivity of the PANI/GNS or CNT coated polyester fabrics increased, while the Seebeck coefcient increased in the measured temperature range from 303 to 338 K. A maximum power factor of ~0.00192 and 0.00076 μWm-1K-2 at 338 K was obtained for the PANI/GNS or CNT coated fabric with 2.5 wt% GNS and 10% CNT loading
