摘要：

Poly(vinylidene fluoride) (PVDF) nanocomposites with different loadings of multiwalled carbon nanotubes (MWNT) were prepared by melt-compounding technique. A homogeneous dispersion of MWNT throughout PVDF matrix was observed on the cryo-fractured surfaces by scanning electron microscopy. Thermogravimetric analysis results indicated that the thermal stability of neat PVDF was improved with the incorporation of MWNT. Dynamic mechanical analysis showed a significant improvement in the Storage modulus over a temperature range from -125 to 75 degrees C with the addition of MWNT. The melt-rheological studies illustrated that incorporating MWNT into PVDF matrix resulted in higher complex viscosities (vertical bar eta*vertical bar), storage modulus (G'), loss modulus (G ''), and lower loss factor (tan delta) than those of neat PVDF.
