| Abstract: | A new type of polymer dispersed liquid crystal (PDLC) composite film has been made by polymerizing the mixture of di-methacrylates, methacrylates containing various groups and E-7. It was found that the long chain alkyl and mesogenic groups in methacrylate monomers greatly affected the saturation and threshold voltages and response time. The sharpness could be improved by addition of methacrylate monomers containing long chain alkyl and 4-butoxylbisphenyl based mesogenic group in appropriate ratios. |
