Mrs. Nazmunnahar Nazmunnahar, in collaboration with Aman Ul Azam Khan, Mehedi Hasan Roni, Aurghya Kumar Saha, Zarin Tasnim Bristy, Abdul Baqui, and Abdul Md Mazid, co-authored a significant study on sustainable smart textile development using e-waste materials. The research focuses on fabricating twelve types of conductive threads by twisting copper filaments with cotton and polyester, followed by coating with carbon paste enriched with sea salt, sourced from recycled dry cell batteries. The developed threads exhibited exceptionally low electrical resistance, with the best-performing variant achieving 0.0164 Ω/cm. Comparative analysis revealed performance equal to or better than commercial conductive threads. The threads maintained stability under bending, twisting, and wash cycles, proving their suitability for wearable electronics, flexible circuits, and eco-friendly textile innovations.
