| 제목 | Effect of Fullerene on the Electro-optical Properties of HPDLC |
| 초록 | Effects of the fullerene on the electro-optic properties of holographic polymer dispersed liquid crystal(HPDLC) have been studied hoping to increase the diffraction efficiency and to reduce the switching voltage. Surfactant and 2,2,2 trifluoroethyl acrylate(TFEA) ware added to the monomer mixture to enhance the phase separation and improve optical properties. The content of fullerene has been systematically varied for HPDLC. The morphology of holographic gratings is examined using atomic force microscopy(AFM) and scanning electon microscopy(SEM). Real time measurements of grating formation have been obtained according to the content of fullerene. By doping ＜1wt% of fullerene, the threshold voltage was decreased and improved the electro-optical qualities were obtained, together with an decrease in response time. |
