Abstract:
Reduced graphene oxide (rGO)@MoS2 composites with a loose structure were prepared and added to poly(vinylidene fluoride) (PVDF) to form composites that showed superior microwave absorption and excellent electromagnetic interference shielding performances. The maximum reflection loss of the rGO@MoS2 /PVDF composites, with a low filling rate (only 5.0 wt %), can reach -43.1 dB at 14.48 GHz, and the frequency bandwidth below -10 dB is 3.6-17.8 GHz (in the frequency range of 2-18 GHz) with a thickness of 1-5 mm. Furthermore, rGO@MoS2 /PVDF composites with a higher filling rate (25 wt %) also exhibit outstanding electromagnetic interference shielding effectiveness, reaching a maximum at 27.9 dB. The mechanism of enhanced absorption and electromagnetic interference shielding performances were also studied in detail.
