Abstract

For the first time, tantalum carbide (TaC) nanoparticles modified pyrolytic carbon fiber (TaC/PyC)_f fabrics were elaborately designed and fabricated through in-situ formation of TaC nanophase on the surface of PyC_f fabrics derived from pyrolysis of cotton fiber clothes. The introduction of highly electrically conductive TaC nanophase significantly improved the electrical conductivity and interaction capability of (TaC/PyC)_f fabrics with electromagnetic waves in terms of reflection and absorption, which leads to a significant increase in the total shielding effectiveness (SE_T). With a thickness of ~260 μm, the best SE_T of the resultant (TaC/PyC)_f fabrics can reach 75.0 dB compared to 24.4 dB of the PyC_f fabrics with otherwise identical conditions. Through employing both the advantages of TaC and C_f, flexible, thin and light-weight (TaC/PyC)_f fabrics possessing excellent SE were obtained.
