mechanical properties and electrical stability.

Abstract

The rapid advancement of communication technologies and wearable applications has increased the demand for high-performance flexible electromagnetic wave absorption materials. Conventional conductive fibers are often constrained by their poor wearability

weak interfacial stability

and limited absorption efficiency

which restrict their reliability and practical applicability in dynamic environments. Herein

a flexible and robust electromagnetic-absorbing fiber was successfully fabricated

via

wet spinning techniques

which integrates multi-walled carbon nanotubes (MWCNTs)

polyaniline (PANI)

and aramid nanofibers (ANFs). Polymerization of PANI on the MWCNTs surface is employed to optimize impedance matching and enhance interfacial compatibility

while ANFs serve as a continuous structural skeleton

improving the mechanical strength and spinnability. The resulting composite fibers exhibited a tensile strength of (202.0±8.0) MPa and an elongation at break of 13.6%±0.9%

stable electrical conductivity under mechanical deformation

and ultrasonic cleaning. Notably

the fiber architecture enables superior electromagnetic wave absorption

achieving a mi

nimum reflection loss of −62.07 dB and an effective bandwidth of 3.24 GHz compared to the powder counterparts

owing to the extended propagation path and multiple scattering within the aligned fiber network. In addition

the composite fibers demonstrated self-extinguishing behavior during combustion

reflecting their inherent flame-retardant characteristics. This study provides a feasible strategy for developing flexible

high-performance electromagnetic wave (EMW)-absorbing fibers for next-generation protective textile materials.
