Analysis of the torsion angle distribution of poly(vinylidene fluoride) in the melt
Journal article, 2012
Analysis of the torsion angle distribution of poly(vinylidene fluoride) (PVDF) structures at temperatures above its melting point is addressed by combining first principles methods, atomistic simulations and laboratory experiments. Amorphous, alpha- and beta-conformations of PVDF structures have been considered. The results from the atomistic simulations as well as the experiments show that there is a larger probability of the PVDF torsions to be near +/- 180 degrees at temperatures above the melting point, which is associated more with the beta-conformation than the alpha-conformation.
