摘要

Conductive cotton fabrics have important applications in the fields of flexible sensors and intelligent wearables. However, the low durability and complex preparation processes of conductive cotton fabrics limit their applications. In this study, a durable conductive cotton fabric was successfully prepared using a one-pot method. First, a stable colloidal solution containing deoxyribonucleic acid (DNA) segments, carboxymethyl chitosan (CMCTS), and Ag nanoparticles was prepared (DNA/CS/Ag). Thereafter, the prepared DNA/CS/Ag colloidal solution was applied to the fabric sample via one-pot strategy. The cotton fabric obtained demonstrated outstanding electrical conductivity and remarkable durability. The surface resistance of the fabricated sample was determined as 13.1 ± 0.7 Ω/sq. Additionally, even after the fabricated fabric endured 800 bending instances, 100 folding rounds, or stretching actions, the surface resistance of the sample showed no substantial decline. Furthermore, the characteristic features of the sample did not obviously change. Consequently, the conductive cotton fabric developed through the one-pot method holds great promise for applications in both the apparel sector and industrial domains.
