Kurzbeschreibung (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 PyCf 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 (SET). With a thickness of similar to 260 mu m, the best SET of the resultant (TaC/PyC )(f) fabrics can reach 75.0 dB compared to 24.4 dB of the PyCf 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.
