Based on the principle of the biomimetic mineralization and with the aspartic acid as the biomolecule inducer, the magnetotactic wood is prepared through the deposition of the MnFe2O4 crystal on the wood surface via the solvothermal method at low temperature. The asprepared wood is characterized by the X-ray diffraction (XRD), the scanning electron microscopy (SEM), the Fourier transform infrared spectroscopy (FT-IR), the vibrating sample magnetometer (VSM) and the vector network analysis (VNA). The results show that the magnetic MnFe2O4 could be deposited on the wood surface to form the magnetotactic wood induced by the aspartic acid under the alkaline solvothermal mineralization at low temperature. A minimum reflection loss of the magnetotactic wood is-12 dB at 15.52 GHz. Simultaneously, the RL is below-12 dB ranging from 14 to 17 GHz. Therefore, the magnetotactic wood would find a great potential application for preventing the indoor electromagnetic wave pollution.
