| Abstract Scope |
Lightweight nanostructured conductors can reduce vehicle weight and lower the energy demands of electric transport. This work develops a hierarchically engineered silver–carbon-nanotube (Ag-CNT) fiber using dry-spinning followed by in-situ Ag-nanoparticle mist infiltration, roll-to-roll functionalization and silver electroplating. The integrated process preserves the one-dimensional CNT scaffold while uniformly embedding AgNPs, forming a tunable core–shell architecture. The fiber achieves 8.7x10⁶ S m⁻¹ conductivity and 4.3x10³ A cm⁻² ampacity at only 0.40 g cm⁻³ density and 0.30 GPa tensile strength, representing a ~220-fold conductivity gains over pristine CNT fibres and a 95.5 % weight reduction per length versus copper cables. The innovative mist infiltration step optimizes Ag-CNT interfacial contact, enhancing electron transport without compromising mechanical integrity. The described scalable, eco-friendly fabrication positions the Ag-CNT fiber conductors as a transformative, energy-saving and light-weight solution for automotive and aerospace power transmission. |
