Electrical behavior of a Teflon AF-DR1/PMMA film-system as nonlinear optical electret

Teflon AF, a new fluoroplastic amorphous materials with many new excellent features, is deposited on the DR1/PMMA sample by spin coating to form a Teflon AF-DR1/PMMA system in order that the poling stability of DR1/PMMA can be improved. In this paper, the experimental results of isothermal surface voltage decay and the thermally stimulated current spectra are reported and discussed.
