摘　　要：以不同粒径的天然鳞片石墨为原料,通过调节反应参数分别制备出一阶的三元FeCl_3-NiCl_2-GICs,系统考察了石墨粒径对FeCl_3-NiCl_2-GICs的导电性能和微波吸收性能的影响。结果表明:FeCl_3-NiCl_2-GICs是一种介电损耗型微波吸收材料,粒径为165μm的一阶FeCl_3-NiCl_2-GICs的最大反射损耗量最大,高达-10.3 d B。在低频范围内,粒径为74μm的FeCl_3-NiCl_2-GICs的吸波性能最好。Ternary FeCl3 - NiCl2 - GICs with 1st stage structures were synthesized by flaky graphite with different grain sizes, and the effects of grain sizes on the electrical conductivity and microwave absorption properties were discussed. The results showed that FeCl3 -NiCl2 -GICs are dielectric loss microwave absorption materials. The maximum theoretical reflection loss of FeCl3 - NiCl2 - GIC with 165μm is - 10. 3 dB. The microwave absorption properties of FeCl3 - NiCl2 - GIC with 74μm are the best in the lower frequency region.
