We prepared single LC cells using the standard planar antiparallel sandwich-like cell configuration. In this, the LC is sandwiched between two glass substrates, each covered with an ITO layer and a polyimide layer. The ITO layers provide conductivity and the rubbed polyimide layers provide an initial orientation and pinning of the LC molecules. The polyimide used was from Nissan Chemicals (ER-1744) for low pretilt angles (1–3°) and high pinning. This yields a planar initial LC director orientation, that is, the director is oriented parallel to the cell surface. The LC layer thickness was controlled by the glass tube spacers of different diameters. Before filling in a cell, the thickness was confirmed using the interference method of cell thickness measurement.⁴³ MLC-2048 from Merck Ltd. was used throughout experiments.
These LC cells were then used to make optical retarders by placing them between crossed polarizers. We chose a geometry wherein the incident light is polarized at a 45° angle with respect to the LC director (shown in Figure 1). This angle ensures maximum light modulation intensity.

Fabrication and Characterization of DFCLC

Check if the same lab product or an alternative is used in the 5 most similar protocols

The host material used for preparing the DFCLC was nematic LC, MLC-2048 (Merck, Fort Kennerworth, NJ, USA), with the clearing point 106.2 °C and f_c = 14 kHz at 25 °C. The chiral dopant S811 (DIC) was doped into the host material at a concentration of 5 wt%. The helical twisting power (HTP) of S811 in MLC-2048 is −14 µm⁻¹. The composite of the DFCLC materials was injected into 10 µm thick cells with anti-parallel alignment layers by capillary action. The alignment layers forced the DFCLC to exhibit an initial planar state. The frequency-dependent light transmission was examined through a probe laser beam, derived from a He–Ne laser system operated at a wavelength of 632.8 nm. Moreover, crossed polarizer schemes were adopted for the electro-optical measurements of the DTSG device. An arbitrary function generator (Tektronix AFG-3022B, Beaverton, OR, USA) was employed to apply frequency-modulated voltages. In addition, transmission spectra of the DTSG were obtained with a fiber-optic spectrometer (Ocean Optics HR 2000+, Orlando, FL, USA) with a halogen light source. All experimental data were acquired at 26 ± 1 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
