Research on UV-cured composite films of epoxy with superparamagnetic, hollow nickel–zinc ferrite nanospheres and their microwave absorption

Epoxy/nickel–zinc ferrite (NZFO) hybrid nanocomposites have been successfully prepared using UV-curing process, and their composition, structure, morphology, magnetic and microwave absorption have been characterized at the same time. The results from FTIR and TGA show that NZFO and the epoxy are uni...

Summary:Epoxy/nickel–zinc ferrite (NZFO) hybrid nanocomposites have been successfully prepared using UV-curing process, and their composition, structure, morphology, magnetic and microwave absorption have been characterized at the same time. The results from FTIR and TGA show that NZFO and the epoxy are uniformly combined by UV-curing process. The magnetic measurement of the epoxy/NZFO nanocomposites reveals that the maximum saturated magnetization is 75.04 emu/cm 3 at room temperature. The composite of 35 wt% (the ratio of NZFO to epoxy/NZFO composite) exhibits excellent microwave absorbing property with a minimum reflection loss (RL) of − 27.66 dB at 9.59 GHz. The nanocomposites show favorable superparamagnetic property and microwave absorption.
