Summary: Polymer dispersed liquid crystals (PDLCs) containing ODA-SWCNT dispersions were prepared and their electro-optical properties were studied. Compared to pure PDLCs, the PDLCs with ODA-SWCNT dispersions showed a shorter response time, lower threshold voltage, higher optical transparency, and better image sharpness in the ON-state.

Summary: This study investigates diffraction gratings of polymer-dispersed liquid crystal with polarization-selective characteristics. Electrically controllable gratings are created using In-Plane Switching electrodes. The number of diffraction orders can be controlled by voltage, and the highest intensity is obtained for every order except the zeroth order. The polarization direction of the diffraction is perpendicular to the direction of the electrode stripes.

Summary: An electroactive despeckle diffuser (EADSD) is demonstrated using a polymer dispersed liquid crystal (PDLC) inplane switched by two pairs of interdigitated electrodes whose directions are orthogonal. The device can reduce speckles more effectively owing to the more diverse electric field introduced by the interdigitated electrodes.

Summary: In this study, a fabrication method for dual-responsive electrochromic (EC) polymer dispersed liquid crystal (PDLC) devices was developed. By combining the PDLC technique and a colored complex formed via a redox reaction, an EC PDLC device was prepared using a simple method. The mesogen in the device played dual roles in scattering and participating in redox reactions. Orthogonal experiments were conducted to investigate the electro-optical performance under different factors, resulting in an optimized device with four switchable states modulated by external electric fields. The color and hue of the device can be modulated by variations of mesogen and ionic salt species, solving the limitation of single color in traditional EC devices. This work lays the foundation for patterned multi-colored displays and anti-counterfeiting using screen printing and inkjet printing techniques.

Summary: Electrochromism is the ability of a material to change its optical properties or color when an external potential is applied. Conventional electrochromic materials based on inorganic materials have drawbacks including single color change, expensive materials, and slow switching speed. To overcome these challenges, conducting polymers (CPs) have emerged as a promising alternative with advantages of multicolor, fast response, low cost, easy processing, and environmental friendliness. This review introduces the current state-of-the-art development of ECDs based on three popular CPs, namely, polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, with emphasis on their synthetic approaches and electrochromic performance.

Summary: This article reports the influence of polymer dispersion on liquid crystals by examining their structural, morphological, and electro-optic properties. The effect of ultraviolet irradiation on the morphological and electro-optic characteristics and perceived structural behavior transformation has been investigated. The physicochemical properties of polymer-dispersed liquid crystal systems are significantly influenced by polymer concentrations and temperature.

Summary: Supercapacitors, known for their high power density, fast charging and discharging speeds, and long service life, are widely used in various fields. However, the integration of supercapacitors in flexible electronics faces challenges regarding extensibility, bending stability, and operability. To address these challenges, we deposited thiophene and 3-methylthiophene on patterned 304 stainless steel through electropolymerization to prepare stretchable conducting polymer electrodes. Moreover, the cycling stability of the electrodes was improved by protecting them with a poly(vinyl alcohol)/sulfuric acid gel electrolyte. The assembled flexible supercapacitors exhibited 93% stability even after 10,000 cycles of strain, highlighting their potential applications in flexible electronics.
