Multi-walled carbon nanotubes (MWCNTs)/fluoropolymer (F2314) composites were prepared via a melt blending process The influences of MWCNTs content on the viscoelastic properties (dynamic mechanical behavior and three-point bending creep properties of MWCNTs/F2314) were explored using dynamic mechanical analysis (DMA) method. The results show that with increasing the MWCNTs content, the storage modulus (E′) of MWCNTs/F2314 composites increases, the glass transition temperature (T_g) and peak value of loss factor (tanδ_max) decrease. The creep strain and constant creep strain rate of MWCNTs/F2314 composites distinctly decrease due to the presence of MWCNTs. At 80 ℃/0.1 MPa, when the MWCNTs content(mass fraction) increases from 2% to 20%, the creep strain and constant creep strain rate of MWCNTs/F2314 composites decrease by 87.6% and 84.7%, respectively. Burger four-element mechanical model can be used to simulate the creep behaviors of MWCNTs/F2314 composites and obtain the constitutive equations of creep curves.
