| Résumé : |
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. |
