文摘
- •
A superparamagnetic hybrid nanocomposite based on Ni–Zn ferrite and polyethylene glycol (PEG) was prepared.
- •
The minimum reflection loss (RL) reaches −50.15 dB with the volume fraction of 35% just at the thickness of 2.9 mm.
- •
The optimal RL is –46.43 dB with the volume fraction of 45%, while the specimen thickness is only 2.2 mm.
- •
A formation mechanism is proposed according to FTIR, XRD, TGA, TEM, SAED and a series of experiments.
