Abstract

Polymorphism in poly(vinylidene fluoride) (PVDF)/clay nanocomposites was studied. Poly(vinylidene fluoride)/clay nanocomposites were prepared with melt intercalation. The samples were characterized with X‐ray diffraction, differential scanning calorimetry, and Fourier transform infrared spectroscopy. The nanocomposite exhibited the Ξ² form. Thermal annealing performed at 125 and 185Β°C showed that the Ξ² form of PVDF was stable. The stability of the Ξ² form of PVDF was ascertained from these studies. The Ξ² form of PVDF in the nanocomposites could be due to crystallization in the constrained phase. Β© 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2036–2040, 2003

Triple-channel solid-state NMR investigations of two di †erent poly(vinylidene Γ‘uoride) (PVDF) materials are described. Carbon-13 cross-polarization magic angle spinning NMR spectra were recorded using simultaneous high-power decoupling on both the proton and Γ‘uorine channels. Both 1H to 13C and 19F

## Abstract 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
