| Abstract: |
In this study, multifunctional polyaniline-methylcellulose@rGO-CuS (PM@rGO-CuS) nanohybrids were synthesized via a facile one-pot method. This approach combined rGO-CuS nanohybrids, aniline monomer, and methylcellulose (MC). By precisely tuning the rGO-CuS fraction, the composite's properties were optimized and thoroughly characterized. The resulting nanohybrids were then applied to cotton fabric in a single-bath process using chitosan (CS). This produced an engineered textile with exceptional electronic properties and a DC conductivity of 4.5 × 10(-5) S/cm. This represents a six-order-of-magnitude enhancement over the original cotton material. Notably, this study presents the first demonstration of tunable negative dielectric permittivity (ε |
