Preparation of an Fe₃O₄ Nanoparticle/Carbonized Hemp Fiber Composite with Superior Microwave Absorption Performance.

ABSTRACT: The increasing concern over the negative impact of electromagnetic radiation and interference on humans has led to a growing interest in microwave-absorbing materials that are cost-effective, have a wide frequency range, and have high efficiency. In this paper, an Fe₃O₄ nanoparticle/carbonized hemp fiber composite was successfully prepared using hemp fibers as the primary material and template. By carefully regulating the concentration of the iron nitrate impregnation solution, accurate loading of Fe₃O₄ nanoparticles onto the carbonized hemp fiber was achieved. Due to its unique porous structure, the balance between impedance matching, and electromagnetic loss, the prepared Fe₃O₄ nanoparticle/carbonized hemp fiber composite
