“…The clearing point of 5CB is 35.3 • C and it can be raised up to about 43 • C after Ag NPs are doped. There is a optimal Ag NPs concentration to get the best transmission and diffraction efficiency, above or below this concentration will result in material properties [21].…”

Holography as a true three-dimensional (3-D) technique is thought to be the ultimate display technique. However, dynamic holographic materials still have problems such as slow refresh, high applied electrical field, etc., to be solved to realize video-rate 3-D display. We present silver nanoparticles (Ag NPs) doped liquid crystal films with very big birefringence and super-fast hologram refresh speed as real-time dynamic holographic medium, which can be applied in holographic video display. And the fastest response time of both build-up and self-erasure of hologram can be up to 0.1 ms, which means the material has the ability to realize a smooth holographic video-rate display. The holographic diffraction efficiency dependent on the intensity of recording light, applied electrical field, etc. is investigated. The maximum diffraction efficiency is measured up to 50% under a low applied electrical field of 0.12 V/μm. Real-time holographic videos at red, green, and blue colors are obtained and the process of hologram formation is analyzed, which shows that the LC films doped Ag NPs can be a good candidate for applications of large-size, real-time, color holographic true 3-D display in future.

“…The combination of polymers and liquid crystals (LCs) can be classified into different configurations via the properties of the polymers, including LC cells with photoconductive polymer films [ 1 , 2 ], LC cells with polymer structures [ 3 , 4 ], polymer-stabilized LCs (PSLCs) [ 5 , 6 , 7 ], polymer-dispersed LCs (PDLCs) [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], and LC elastomers [ 19 ]. PDLC films that comprise LC droplets dispersed in polymers are formed due to the light-induced phase separation in the precursors of the PDLCs.…”

“…The transmittances of the PDLC films can be modulated by external voltages, and polarizers are not required at the transmittance modulation. Therefore, PDLC films have potential in developing electro-optic devices such as displays [ 8 , 9 , 10 , 11 , 12 ], lenses [ 13 , 14 ], sensors [ 15 , 16 ], gratings [ 17 , 18 ], lasers [ 20 , 21 , 22 ], and light modulators [ 23 , 24 , 25 ].…”

An organic solvent sensor of polymer-dispersed liquid crystals (PDLCs) film is fabricated by a combination of tri-functional monomers and LCs. When the patterned PDLC film comes into contact with the organic solvent, the organic solvent will penetrate into the film to induce the orientation of the liquid crystals, which will change from an ordered to a disordered state, which causes the PDLC film to scatter incident light. The experiment used acetone and ethanol as the organic solvents of interest. The results show that the patterned PDLC film has a stronger response to acetone than to ethanol. Based on the difference in the intensity of light scattering and the response time of the patterned PDLC film to different organic solvents, the results can be used to identify and recognize different types of organic solvents.
