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.

首次通过在棉纤维衣服热解衍生的PyC _f织物表面上原位形成TaC纳米相，精心设计和制造了碳化钽（TaC）纳米颗粒改性热解碳纤维（TaC / PyC）_f织物。高导电性TaC纳米相的引入显着提高了（TaC / PyC）_f织物在反射和吸收方面的电导率和与电磁波的相互作用能力，这导致总屏蔽效率（SE _T）大大提高。厚度约为260μm时，最好的SE _T（TaC / PyC）_f在其他条件相同的情况下，PyC _f织物可以达到75.0 dB，而PyC _f织物为24.4 dB 。通过同时利用TaC和C _f的优点，可以获得具有优异SE的柔软，薄且轻的（TaC / PyC）_f织物。
