Polymer-dispersed liquid crystal elastomers

The need for mechanical manipulation during the curing of conventional liquid crystal elastomers diminishes their applicability in the field of shape-programmable soft materials and future applications in additive manufacturing. Here we report on polymer-dispersed liquid crystal elastomers, novel composite materials that eliminate this difficulty. Their thermal shape memory anisotropy is imprin...

Nanoparticle-doped polymer-dispersed liquid crystal display

Polymer-dispersed liquid crystals (PDLCs) represent an important new class of materials for optical device applications. Their valuable advantages such as low operating voltage, high contrast ratio, requiring no extra optical elements (i.e. polarizer), quick electrooptical response, no leakage of materials, simple fabrication, low-cost production and ease of processing make them more popular ov...

Carbon Nanotube Macroelectronics for Active Matrix Polymer-Dispersed Liquid Crystal Displays.

Active matrix liquid crystal display (AMLCD) is the most widely used display technology nowadays. Transparent display is one of the emerging technologies to provide people with more features such as displaying images on transparent substrates and simultaneously enabling people to see the scenery behind the panel. Polymer-dispersed liquid crystal (PDLC) is a possible active matrix transparent di...

Controlling the anisotropy of holographic polymer-dispersed liquid-crystal gratings.

In this work we investigate the optical properties of electrically switched transmission gratings fabricated holographically using polymer-dispersed liquid-crystal (PDLC) materials. We have found that the PDLC mixture can be used to control the diffractive properties of the liquid-crystal composite gratings. In one limit the gratings are highly isotropic and in the other limit the gratings are ...
