||Writing Two-Dimensional Patterns into Diacrylate Mesogens Using 632.8 nm He-Ne Laser|
|Date of Defense
polymer liquid crystal
||Diacrylate (RM82) is a thermotropic polymer liquid crystal, which consists of photoactive mesogenic end groups. Inducing of light, RM82 formed polymers by polymerization reaction. |
Low power He-Ne laser induced holographic optical field , forming a periodic grating and recording into RM82 film in previous study. Further, we hope to be able to produce the patterns which can be controlled in the film. Because of the diffusing phenomenon of Free-Radical, when we irradiated first area, the polymerization area which we undesired diffused out of the irradiated zone.
Therefore, we consider the study of a single beam of He-Ne laser in RM82 multi-point writing in this study, by changing the exposure time and the two irradiation distance in order to control the diffuse of the polymerization region , and writing a complete two-dimensional patterns into RM82.
