| Abstract: | The large size liquid crystal droplet of polymer dispersed liquid crystal(PDLC) films with piezo-optical effect is prepared,the photographs of polarization microscope with press compared with that one without press are given.The model of compressed liquid crystal droplet is proposed,the order of flattening that liquid crystal droplet turns from pellet to the flat one after compressed is defined,the relation between the order parameter and order of flattening with compressing is calculated.The transmittance ... |
