Abstract :
A series of PPFC (plasma-polymerized fluorocarbon) film materials having widely varying compositions and properties was studied. Fluorine-rich (Teflon-like) films (F/C≳1.7) were found to have relatively low degrees of oxidation, as manifested by their infrared and XPS spectra. Strong correlations between film compositions and their electrical properties were found. The TSD spectra of PPFC films are reported: the α and β relaxations observed near 50°C and -80°C, respectively, correlate well with dielectric relaxations corresponding to carbonyl dipoles and to local motions of fluorocarbon chain segments observed by other workers. The charge storage time constants shows rough correlation with F/ C; the large scatter of data, however, suggests that this relationship should be the object of further studies
