Dielectric and electro-optical properties of polymer-stabilized liquid crystal system

Improvement of Electro-Optical Properties of PSLC Devices by Silver Nanowire Doping

“…In application, PSLC devices, which are transparent without electric field, are more economical and convenient than PDLC devices. Furthermore, PSLC devices have lower threshold voltage, shorter response time, higher contrast and wide viewing angle [13], making them also widely used as displays, spatial light modulators, hologram-formed light modulators [14], temperature sensors [15], flexible displays [16], and other devices besides smart windows.…”

Electro-optic properties of polystyrene particle-laden polymer-stabilized liquid crystals

“…According to the table, the addition of the polymer network resulted in a 6-fold increase in the threshold voltage. Such behaviour is typical for PSLCs 8,9,37–41 and can be explained by an increase in the internal surface area. Indeed, the polymer strands provide an additional surface which interacts with the liquid crystal molecules and, like the orientation layers, keeps the molecules parallel to itself.…”

Molecular engineering of the polymer stabilizing network to enhance the electro-optic response of cholesteric liquid crystals

“…The real part of the dielectric constant (e 0 ) is related to the ability of the system to store energy (capacitance) while the imaginary part (e 00 ) is related to the energy loss in the system through charge movement (conductivity). 40 We employ the calculated effective conductivity (s eff , eqn ( 5)) to study the effect of ion-trapping by the comonomers.…”

“…The real part of the dielectric constant ( ε ′) is related to the ability of the system to store energy (capacitance) while the imaginary part ( ε ′′) is related to the energy loss in the system through charge movement (conductivity). 40 We employ the calculated effective conductivity ( σ eff , eqn (5)) to study the effect of ion-trapping by the comonomers. σ eff = ωε ′′where ω is the angular frequency and the calculation is completed by fitting the data to the linear region at lower frequencies in the log–log plot. 41 Selected dielectric plots and calculated σ eff for CLCs and PSCLCs are shown in Fig.…”
