Electronic textiles combine the advantages of flexibility in textiles and the performance of electronics in a wearable form for sensing applications. We report an inexpensive and straightforward coating method of pre-treatment, dipping, and drying the cotton yarn, combining the advantages of polypyrrole/carbon black, while investigating the mechanical, in situ electrical properties, and thermal conductivity of polypyrrole/carbon black composite coated cellulose (cotton) yarn. The coated yarn is mechanically stable with the tensile strength of∼11.6 N. The resistivity and conductivity properties of the yarn are measured from the linear response of the I–V curve, showing an ohmic behavior. Further, the coated surface was tested using scanning electron microscopy for uniformity in the surface coating. Thermal conductivity for the coated fabric was measured using Transient-hot-bridge method and measured to be 0.12 Wm−1 K−1 at ambient temperature.
