Journal Article 2025 12 15 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. https://ppam.semnan.ac.ir/article_10657_eff78b1dcdd66a563616e3cdb08dcb8f.pdf
