Abstract
Herein, the morphological, electrical, thermal, and structural properties of conductive threads prepared using PEDOT:PSS, SWCNTs, and a layer combination of both are investigated. The primary finding of this work is that the layer thread has lowest resistance of 0.0072 omega compared with 0.0211 omega for SWCNTs alone and 0.0528 omega for PEDOT:PSS alone. This lowest resistance is achieved with 1.729 mg of constituent compared with 1.870 mg of SWCNTs and 79.81 mg of PEDOT:PSS to obtain the respective resistances of 0.0211 and 0.0528 omega. The layer thread therefore achieves lowest resistance with the least amount of material, in particular PEDOT:PSS. All resistances exhibit metallic behavior as a function of temperature up to 90 degrees C, and this behavior is stable for a period of at least 3 months.
