摘要：
The surface modified Fe-Si-Al alloy flakes with nylon 6 were prepared by a simple melt compounding method, and the electromagnetic and microwave absorption properties were presented. After surface modification, the complex permittivity of the flakes decreases dramatically with increasing amount of nylon 6, while the complex permeability remains nearly intact. The calculated microwave reflectivities show that surface modification is able to improve the microwave absorption performance of Fe-Si-Al flakes and that the composite containing modified flakes with an appropriate amount of nylon 6 is a promising candidate for a thin microwave absorbing material in S-band (2-4 GHz).
