A possibility for ferroelectric twinning of 60° domains existing in the phase-I crystallite of poly(vinylidene fluoride) has been examined by the use of an x-ray diffraction method. Interdomain interference causes anomalous splitting of the calculated diffraction peaks. Anomalous changes in the profiles are observed for the crystallites in a film under electric fields up to 120 MV/m, and can be explained in terms of the twin structure.
