Abstract

In this study, we synthesized three-dimensional porous-network composites containing reduced graphene oxide (rGO) and Fe₃O₄ nanoparticles (rGO/Fe₃O₄) via hydrothermal and freeze-drying processes. These were then introduced into a smoke canister, and colloidal silicone rubber (RTV-615) was used as an infrared (IR) and microwave (MW) absorber. The infrared shielding effectiveness was investigated by measuring the thermal extinction in the smoke canister for dynamic testing using a thermal imager in the 8–12 μm range. The microwave-absorbing properties were investigated by measuring the reflection loss in the 2–18 GHz range with a network analyzer using the free space method. For the rGO/Fe₃O₄ composite with concentrations of 1–3 mg/cm³ and 1 mg/cm³, the thermal extinction reached 30–43 °C and 26–35 °C in static testing and dynamic testing, respectively. The rGO/Fe₃O₄(1:2) composite exhibited a maximum absorption value of −31.3 dB at 15.3 GHz at a thickness of 2.0 mm.
