摘要：

The magnetic functionalized rGO/Fe3O4 was prepared by hydrothermal method with graphene oxide and ferric chloride as raw materials, and subsequently rGO/Fe3O4 particles were blend in epoxy resin to prepared composite rGO/Fe3O4/epoxy resin. The results show that the impact strength of rGO/Fe3O4/epoxy resin composites reaches 27 kJ/m2 when the addition amount of rGO/Fe3O4is 30%, which is 58.8% higher than that of the plain epoxy resin. In addition, the absorption performance of epoxy resin composite is significantly enhanced after the addition of rGO/Fe3O4. When the addition of rGO/Fe3O4 is 20%, the reflection loss of the rGO/Fe3O4/epoxy resin composite is less than −10 dB in the frequency range of 7.7~12.3 GHz. The effective absorption bandwidth (reflection loss<−10 dB) is up to 4.6 GHz, which covering the whole X-band. With the increase of graphene content, the position of the minimum reflection loss of rGO/Fe3O4/epoxy resin composites moves towards low-frequencies. It follows that by controlling the relative content of rGO and Fe3O4, the absorbing performance of rGO/Fe3O4/epoxy resin composites can be adjusted to the meet the requirements for materials of desired absorbing performance. © 2022 Chinese Journal of Materials Research.
