Development and evaluation of BaFe12 O19-PANI-MWCNT composite for electromagnetic interference (EMI) shielding

The salient individual properties of BaFe12 O19, MWCNT, and PANI show promise in exhibiting excellent electromagnetic interference (EMI) shielding when they are combined. This research work focuses on developing a composite consisting of all three materials through a simple polymerization process an...
