“…Research into the properties of liquid crystals doped with ferroelectric nanoparticles, initially undertaken by European and American scientists mostly, received a considerable boost due to the contributions coming from China, India, Iran, Taiwan, South Korea, and Japan. Several papers published in 2010–2011 [ 53 , 55 , 61 , 66 ] were followed up by an even greater number of publications [ 67 , 70 , 78 , 79 , 81 , 88 , 97 , 100 , 102 , 104 , 107 , 110 , 111 , 116 , 117 , 119 ]. For example, low voltage and hysteresis free blue phase liquid crystals doped with ferroelectric nanoparticles were reported [ 67 , 97 ].…”

“…During the 2012–2017 time period the variety of materials used in experimental studies continued to grow. Polymer stabilized blue phase liquid crystals [ 97 ], polymer dispersed liquid crystals [ 88 , 110 , 111 ], and bent-core liquid crystals [ 122 ] doped with barium titanate (BTO) nanoparticles were studied. Moreover, lithium niobate (LNO) and multi-ferroic nanoparticles were introduced as ferroelectric dopants [ 85 , 99 ].…”

“…From a general point of view, these NPs behave as impurities affecting to the presence and mobility of ions in the mixture. In this sense, the presence of nanomaterials produces an enhancement of the dielectric anisotropy [15], reduction of the threshold voltage [16], and also other interesting effects like frequency modulation [17] and memory effect [18]. Besides these properties, which may be interesting for display applications, other properties could be affected by the presence of the nanomaterials.…”

“…LC-based VOAs are attracting considerable interest owing to their favorable properties, such as an absence of moving-parts, low power consumption, and ease of fabrication. Two common mechanisms of attenuation of light intensity in existing LC-VOAs are based on optical absorption and scattering properties [11][12][13][14][15][16]. The former normally requires the use of dichroic dyes or polarizers to absorb light.…”

“…In contrast, the latter exhibit polarization-independence and broadband operation (~few hundred nanometers). The most widely used techniques in realizing scattering-type LC-VOAs is to adopt liquid crystal/polymer composites, including polymer-dispersed liquid crystal (PDLC) [12,13], polymer network liquid crystal (PNLC) [14], and polymer-stabilized cholesteric liquid crystal (PSCLC) [15,16]. After phase separation in liquid crystal/polymer composites, polymer networks or LC droplets are generated, depending on the adopted polymer materials, and so optical scattering occurs as a result of the mismatch of the refractive index in the polymer and the LCs.…”
