An investigation on an epoxy - based PDLC film's fabrication and its properties

In this paper, polymer dispersed liquid crystal (PDLC) films were prepared by the method of polymerization induced phase separation (PIPS). Through optimizing the fabrication of PDLC including the content of liquid crystal (LC), the curing temperature and the curing time, we studied the factors which affect directly on the PDLC's electro-optic properties. The physical characteristics, the phase separation and the electro-optic properties of PDLC were characterized by UV-Vis spectroscopy, AFM and SEM etc. PDLC will have a wider perspective in the fields of sensor,electro-optical switch,grating and new generation analytical apparatus.
