The composites were synthesised by a two-step hydrothermal and in-situ polymerisation method, with Zn ferrite (20-30nm particles) used to adjust the impedance matching and improve polyaniline magnetic loss capability.

“The synergy of fluffy structure, dielectric loss, magnetic loss, interfacial polarisation and phase cancellation effect lead to the attenuation of microwave energy,” according to the University. ” Furthermore, the fluffy structure enhanced the microwave transmission path and attenuation efficiency. These factors make this composite a good microwave absorber and an ideal material in the electromagnetic wave absorption field.”
