Paper Abstract

Based on a novel concept that intensive optical field may improve alignment of polymer films photopolymerized by linearly polarized laser light, we investigated effects of instantaneous intensity of the laser light and viscosity of the films on alignment of liquid crystals on the photopolymerization-induced anisotropic films. The intensity and the viscosity are the two essential factors related intimately to magnitude and relaxation time of the reorientation Kerr effect. The experiments demonstrated that the increase in the intensity and the decrease of the viscosity improved the photopolymerization-induced orientation of the films. Based on the photochemical points, we discussed causes of the improvement.
