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 (PyCf 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 PyCf fabrics while the tensile strength increased to 5.63 +/- 0.16 MPa compared to 0.73 +/- 0.10 MPa of pristine PyCf 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.
