In this work, activated carbon (AC) and pyrrole were successfully deposited onto cotton fabric using simple dip and dry methods. First, the fabric was bleached. Next, a mixture of AC derived from rice husk, polyvinyl alcohol (PVA) as a binding agent, and sodium dodecylbenzene sulphonate (SDBS) as a surfactant was prepared. This mixture was applied to the fabric using a brush. After that, the AC treated fabric was submerged in a pyrrole solution of the desired molarity, followed by immersion in a ferric chloride (FeCl₃) solution for 2 h. Four samples were prepared, and structural, morphological, and electrical characterisation was performed using field emission scanning electron microscopy (FESEM), energy dispersive X ray spectroscopy (EDX), and Fourier transform infrared (FTIR) spectroscopy. Electrical characterisation was conducted using a four point probe method at room temperature for 2 min on 1 × 1 cm² samples. Among all the samples, PPy/AC/cotton fabric (2) exhibited the highest conductivity of 5.5 S/cm. The study also demonstrated that increasing the molarity of pyrrole and FeCl₃ initially enhanced the conductivity. However, when the molarities were increased to 0.3 M pyrrole and 0.6 M FeCl₃, as well as 0.4 M pyrrole and 0.8 M FeCl₃, the conductivity decreased, and the fabric became stiffer and more rigid.
