“… 5 , 6 , 7 For the MA materials, the traditional metals have inherent limitations such as impedance mismatching, large size, high density and lack of corrosion resistance, such as Fe, Co, Ni, 8 and Fe 3 O 4 9 , 10 , 11 , 12 hinder their practical application. Recently, fibrous materials, e.g., carbon fibers 13 , 14 and silicon carbide fibers 15 , 16 have attracted extensive attentions and show a great potential in MA beneficial from light weight, high conductivity, good mechanical properties, as well as the structural featured with large specific surface area easy to compound with other materials.…”
