Abstract
Holographic polymer dispersed liquid crystal (HPDLC) is a kind of novel photoelectronic information materials. The diffraction efficiency (DE) can be modulated by the application of electric field. HPDLC devices are potentially useful for optical communication, panel dipslay, information storage and integrated optics. The diffraction efficiency plays an important role in application of HPDLC. Based on the phase separation process of HPDLC and the morphology observed by the scanning electronic microscope (SEM), the diffractive character was studied. We investigated the dependence of diffraction efficiency on different monomers, exposure intensity, liquid crystal loading and curing temperature. The best conditions were founded to make the diffraction properites optimized and the highest diffraction efficiency 80.2 percent was gotten.
