Ultrathin and Lightweight Functionalized CNF Mixed Barium Ferrite Nanocomposite for Stealth Applications
This work, presents investigation of microwave properties of an advanced magneto-dielectric nanocomposite synthesized by dispersing functionalized carbon nano fiber (CNF 0.0,0.5,1 and 2 wt.parcent) along with barium ferrite nanoparticles (50 wt. %) into epoxy polymer matrix. The FESEM image of nanocomposites showed non-uniform distribution of nanofillers in the epoxy matrix. The real and imaginary part of permittivity increases with increase in CNF concentration, without significantly affecting the magnetic permeability of the nanocomposite samples. Among, all nanocomposites, the 50wt.% nanocomposite samples. Among, all nanocomposites, the 50wt.% wide absorption bandwidth (-10 dB) of 2.50GHz at 1.5mm thickness in X-band.
