The ferroelectricity effect of nanoparticles on thermodynamics and electro-optics of novel cyanobiphenyl eutectic binary mixture liquid crystals

Thermodynamic study of the effects of nanoparticles on thermal origin: A review

“…It was found that enhancing the properties of HAT4-copper hybrid nanoparticles are beneficial for one dimensional conduction, and photovoltaic applications. Dalir, Javadian [99] conducted research to investigate the ferro-electricity nanoparticles of both the thermodynamics and electro-optics of a novel mixture of cyanobiphenyl eutectic binary liquid crystals. It was observed that there is a clear difference in terms of thermodynamic properties and the temperature of nematic-isotropic phase transition , which includes enthalpy as well as entropy changes, between the pure and doped compounds.…”

Ferroelectric Nanoparticles in Liquid Crystals: Recent Progress and Current Challenges

“…For example, low voltage and hysteresis free blue phase liquid crystals doped with ferroelectric nanoparticles were reported [ 67 , 97 ]. Interesting effects of ferroelectric nanoparticles on the luminescence and electro-optics of ferroelectric liquid crystals were observed [ 78 , 81 , 85 , 89 , 90 , 95 , 96 , 105 , 106 , 107 , 108 , 109 ], and theory of (i) nanoparticles in ferroelectric liquid crystals [ 79 ]; (ii) the effect of ferroelectric nanoparticles on the isotropic-smectic-A phase transition [ 104 ] and the Freedericksz transition in smectic-A liquid crystals [ 119 ]; and (iii) the dielectric permittivity in the isotropic phase of the isotropic-smectic-A phase transition were also developed [ 117 ].…”

“…The effects of ferroelectric nanoparticles on the properties of a single component liquid crystal such as 5CB still remain among major research interest [ 72 , 107 , 108 ]. Electro-optics (including the Freedericksz transitions in nematic and smectic-A liquid crystals) [ 98 , 119 ]; dielectric [ 85 , 102 , 105 , 118 , 123 ], electrical [ 85 , 86 , 92 , 93 , 100 , 102 , 103 , 107 , 116 , 121 , 122 ], and viscoelastic [ 90 , 96 , 122 ] properties; phase transitions and pre-transitional effects [ 80 , 94 , 95 , 96 , 107 , 112 , 113 , 118 , 122 , 123 ] in liquid crystals doped with ferroelectric nanoparticles are also receiving due attention during this time period. Another new direction gaining interest of the scientific community includes studies of hybrid liquid crystal-ferroelectric nanoparticles composite materials in the terahertz and microwave regions [ 91 , 120 ].…”
