Studies of temporal stability of poled nonlinear optical polymer films

Guest-host polymer system with potential use in electro-optic devices is discussed. The polymer host is a polyimide and the guest chromophore is Disperse Red 19 (DR 19). Decay times of poled order after corona poling procedure have been derived from the behaviour at elevated temperatures below glass transition temperature Tg using Arrhenius plots. An extrapolated lifetime greater than 30 years at room temperature has been obtained.
