▎ 摘  要

Magnetic paper manufactures are nowadays widely used in information storage, electromagnetic shielding and security industry for its outstanding performances. In this article, Tb-doped germanium borosilicate glass was prepared by melt quenching technique and they were used as magnetic sources of magnetic paper to loading into the bamboo fibers. Magnetic paper has been successfully produced by adding inorganic magnetic particles modified by different concentrations of graphene oxide (GO) solution. The samples were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Raman Spectroscopy, Superconducting Quantum Interferometer Device (SQUID) and Scanning Electron Microscope (SEM). The results shown that the structure of magnetic particle are made from [BO3], [BO4], [A1O(6)], [SiO4] and [GeO4]. GO sheets had been successfully immobilized on magnetic particles (MPs) surface via electrostatic interaction. SQUID indicated that the magnetic particles and papers were paramagnetic materials. SEM images clearly shown that the MPs loaded into the lumen of bamboo fibers and the interstitial of fibers. Bridge-fibers that connecting other cellulose fibers and MPs by hydrogen bonds were formed in the network of paper due to the functional groups on surface of magnetic particles. The mechanical properties of papers increased with the increment of GO concentration, which is correlated with the hydrogen-bonding that forming by bridge-fibers and other cellulose fibers in network of paper.
