Single-walled CNTs have been incorporated in fabrication of conventional holographic polymer dispersed liquid crystals (HPDLCs) and the effects have been studied in terms of grating formation dynamics, morphology, diffraction efficiency, and electro-optical properties of the films. Droplet size decreased with increasing the CNT particles due to the slow rate of polymerization and phase separation. In the presence of CNTs, decreased droplet size with increased droplet density augmented off state diffraction, while increased local electric field overcome the threshold and reduced operating and saturation voltages. Also, both decay time and rise time decreased with CNTs due respectively to the increased local electric field and decreased droplet size. |
