摘要
Core-shell structured γ-Fe2O3@C nanorod-carbon sphere composites have been synthesized via a facile hydrothermal method employing FeCl3·6H2O as the iron source and d-glucose as the carbon source. The core–shell structured γ-Fe2O3@C nanorods possess a uniform size with ∼500–800 nm in length, the carbon shell's thickness is ∼3–10 nm, and the γ-Fe2O3 core is homogeneously coated by amorphous carbon layer. The measured electromagnetic (EM) parameters show that its maximum reflection loss (RL) can reach −8.11 dB at 3.92 GHz. This is mainly attributed to the multiple-interfacial polarization among the core–shell structured γ-Fe2O3@C nanorod-carbon sphere composites. The core–shell structured γ-Fe2O3@C nanorod-carbon sphere composites can be a promising candidate for lightweight microwave materials.
