Abstract

Highly flexible, light-weight, and mechanically enhanced Mo₂C modified PyC fiber (Mo₂C/PyC)_f fabrics with excellent electromagnetic interference shielding effectiveness (EMI SE) and enhanced mechanical strength were prepared via precursor infiltration and pyrolysis (PIP) method. The introduction of Mo₂C significantly improved the EMI SE and tensile strength of the resultant fabrics compared to the control test sample (PyC_f fabrics) prepared under identical conditions. At the thickness of 0.5mm, the EMI SE of the resultant (Mo₂C/PyC)_f fabrics can reach 40.7 dB compared with 14.0 dB of PyC_f fabrics while the tensile strength increased to 5.63 ± 0.16 MPa compared to 0.73 ± 0.10 MPa of pristine PyC_f fabrics. When the thickness of the resultant sample increased to 1.5 mm, the EMI SE in the X band was analyzed up to 60.0 dB with a mean value of 51.2 dB.
