The structures and electronic states in all polymorphs of poly(vinylidene fluoride) (PVDF) were calculated by density functional theory with the generalized gradient approximation combined with Hartee-Fock exchange energy at the Perdew-Burke-Ernzerhof zero-parameter hybrid functional level using the CRYSTAL 09 software. The calculated lattice constants agreed well with experimental values. Derived electronic and phonon dispersions correspond closely with the experimental valence X-ray photoelectron and infrared (IR)/Raman spectra, respectively. The amount of spontaneous polarization in polar crystal forms was determined and the effect of long-range Coulomb interactions were discussed. The calculation method used in this report was confirmed to be precise and shows promise for examining ferroelectric polymers.
