Optically transparent bamboo with magnetic properties

In this study, an optically transparent magnetic material, i.e., magnetic transparent bamboo (MTB), was prepared by innovatively adding Fe 3 O 4 nanoparticles on the basis of transparent bamboo (TB). The delignified bamboo templates were filled with the epoxy resin and Fe 3 O 4 nanoparticles, MTB was tested, and the results were analyzed. The MTB with 2 wt% Fe 3 O 4 nanoparticles was considered to have the best comprehensive performance, having excellen optical properties with the light transmittance of 68.6%, haze of 49.4%, and a high tensile strength of 70.9 MPa. At the same time, it had a certain magnetic strength of 0.73emu/g, and the thermal conductivity of 0.213W/mk. Additionally, the effect of the amount of Fe 3 O 4 nanoparticles on the performance of MTB was investigated, providing the possibility of MTB applications in the magneto-optical fields, e.g., magnetic switches, electronic devices or building materials .
