Dielectric properties of novel poly(aryl prehnitimide)s
Abstract
Six different variants of a new type of polyimide, poly(aryl prehnitimide)s, containing various moisture contents have been studied using dielectric relaxation spectroscopy. Dielectric loss measurements show the presence of a double peak near 200 K (depending on frequency) due to water relaxation. The two peaks have been designated γ1 and γ2. The γ2 peak appears as a shoulder on the γ1 peak at lower temperatures and is very sensitive to …
