Nanographite-zinc particles in various ratios were synthesized by high energy ball milling and dispersed in epoxy based aero grade resins for studying their microwaves absorption in the lower frequency band of 2–9 GHz using a coaxial waveguide measurement system. Morphological characterizations of the synthesized particles showed that shuttle shaped zinc is well embedded on the exfoliated nanographite particles without any agglomeration. The higher interfacial polarization of both the graphite and zinc particles contributes to the excellent electrical conductivity and hence refers it as an ideal microwave absorber in defense applications. The paint with 20% (w/v) loading of nanographite-zinc (1:1 ratio) particles is proficient in providing microwave absorption of − 18.06 dB at 8.19 GHz with a coating thickness of 1.43 mm.

通过高能球磨合成各种比例的纳米石墨-锌颗粒，并将其分散在环氧树脂基航空级树脂中，以使用同轴波导测量系统研究其在2–9 GHz较低频段的微波吸收。合成颗粒的形态学表征表明，穿梭形锌很好地嵌入到剥落的纳米石墨颗粒上，没有任何团聚。石墨和锌颗粒的较高界面极化有助于出色的导电性，因此，它是国防应用中的理想微波吸收剂。负载有20％（w / v）纳米石墨锌（1：1比例）颗粒的涂料，在涂层厚度为1.43 mm时，在8.19 GHz时可提供− 18.06 dB的微波吸收。
