Abstract: The magnetic γ-Fe2O3 nanoparticles are successfully deposited on the surface of the wood via a chemical co-precipitation method with Fe3+ and Fe2+ salts as precursors at the room temperature and with a modification, which show good hydrophobic properties. The scanning electron microscopy(SEM), the X-ray diffraction(XRD), the Fourier transform infrared spectroscopy(FT-IR), and the vibrating sample magnetometer(VSM) are employed to characterize the features of the grown magnetic nanoparticles on the surface of the wood. The SEM images show that the shape of magnetic particles is granular. The XRD spectrum shows that the γ-Fe2O3 nanoparticles with good crystalline are successfully grown on the wood surface. The magnetic γ-Fe2O3 nanoparticles display good superparamagnetic behavior and are chemically bonded to the bamboo surface through the combination of the hydrogen groups. After modified, the magnetic wood material has good superhydrophobic properties.
