Determination of mean dipole orientation in PVDF films by infrared spectroscopy

摘要

AbstractBased on the relations between the intensities of the PVDF bands at 445 cm−1and 510 cm−1, respectively, and the CF2dipole orientation angle, an algorithm is given which allows quantitative determination of the mean dipole orientation. This algorithm is used to calculate the changes in the mean dipole position caused by application of an electric fi
