▎ 摘　　要

Few-layer graphene sheets/poly(vinylidene fluoride) (FGS/PVDF) composites were prepared by a water vapor induced phase separation (WVIPS) method. The composites were investigated by SEM, TEM, FTIR, Raman, XRD, TG, analysis. The analytical results showed that the FGS were uniformly distributed in the PVDF forming continuous network structure in the PVDF matrix, as a direct result of the WVIPS method. The introduction of FGS was found to endow the PVDF with satisfactory electrical conductivity and good electromagnetic interference shielding effectiveness (EMI SE). The composites with 15 wt% FGS content exhibited an electrical conductivity of 1.68 S cm(-1). In addition, the same composites showed the excellent EMI SE in the X-band frequency region (high as 45.6 dB at 10 GHz). The proposed preparation process was found to be an easy, convenient and efficient synthetic route to prepare FGS/PVDF composites, that prove useful in the preparation of similar FGS/polymer composites.
