Correlation between EMI shielding and reflection loss mechanism for carbon nanofiber/epoxy nanocomposite

The lightweight, carbon nanofibers (CNFs∼1, 2, 2.5, 3, and 4 wt.%) are dispersed into the epoxy matrix to synthesize nanocomposites for microwave absorption and EMI shielding application. The FESEM shows, non-uniform distribution of CNFs in the epoxy matrix. The 2.5 wt.% CNF/epoxy nanocomposite attains a maximum tensile strength of 43.22 MPa. On increasing CNFs concentration, the real part of permittivity increases due to high interfacial...
