Abstract
Surface potential technique was applied to determine the orientational order of NLO chromophores in poled polymers. The technique is sensitive enough to detect the electro-optic coefficient of the order of 10-3 pm/v and it is simple because it does not use any optics. It is purely electrical in contrast with other techniques. Relaxation behavior of poled DR1(1wt%)/PMMA was investigated using the surface potential technique. When the surface of the poled polymer was free from a metal electrode, the surface potentials decay monotonically with time. However, the surface potential measured on a metal electrode which was used as an electrode for poling showed an abnormal decay behavior. It was explained by the charge trap centers at the metal-polymer interface.
