摘要：In this paper, a comprehensive experiment for senior students majoring in material chemistry was introduced, which aims to improve the experimental and scientific research abilities of undergraduates. Fe3O4 microspheres were prepared by hydrothermal process with FeCl3·6H2O as raw material and ethylene glycol as solvent and reductant. After Fe3O4 particles were modified by imidazoline surfactant quaternary ammonium salt of 2-undecyl-1-dithioureido-ethyl-imidazoline (SUDEI), Au nanoparticles were attached on the surface of Fe3O4 microspheres, and the Fe3O4@Au composites could be obtained. The composites were characterized by scanning electron microscope (SEM), energy dispersive spectrometry (EDS) and transmission electron microscope (TEM). The photothermal properties of the composites were also investigated. It was found that the composites showed good magnetic property and photothermal conversion property, and the corresponding conversion efficiency can reach up to 21.2%.
