Abstract

The effect of the discharge-generated electric field on dopant orientation in corona poled amorphous polymers doped with nonlinear optical chromophores has been examined using second harmonic generation (SHG), or frequency doubling. The magnitude of the SHG intensity is sensitive to dopant orientation in the glassy polymer matrix. Positive (+) and negative (-) polarity coronas are used to pole films in different atmospheres over a range of poling temperatures (T_p) between 25°C and 110°C. The decay of the surface voltage (V_s) was measured with time following poling. Systems examined include poly(methyl methacrylate)(PPMA) doped with the well characterized chromophore 4-dimethylamino-4′-nitrostilbene (DANS). Both surface voltage and polymer matrix effects influence dopant orientation in the amorphous polymer, with both surface charge and polymer relaxations a function of time and temperature.
