Liquid crystal - Wikipedia
WebLiquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal can flow like a liquid, but its molecules may be oriented in a common direction as in solid.

WebMar 12, 2024 · Liquid crystal, substance that blends the structures and properties of the normally disparate liquid and crystalline solid states. Liquids can flow, for example, while solids cannot, and crystalline solids possess special symmetry properties that liquids lack. Ordinary solids melt into ordinary.
WebLiquid crystal materials are unique in their properties and uses. As research into this field continues and as new applications are developed, liquid crystals will play an important role in modern technology. This tutorial provides an introduction to the science and applications of these materials. What are Liquid Crystals?

WebJan 30, 2023 · Properties of Liquid Crystals. Liquid crystal phases are generally cloudy in appearance, which means that they scatter light in much the same way as colloids such as milk. This light scattering is a consequence of fluctuating regions of non-uniformity as small groups of molecules form and disperse.

WebOct 1, 2018 · Liquid crystals, which are obtained by melting a crystalline solid, are called thermotropic. Liquid crystalline behavior is also found in certain colloidal solutions, such as aqueous solutions of tobacco mosaic virus and certain polymers. This class of liquid crystals is called lyotropic. For lyotropic liquid crystals the important controllable ...

WebSep 9, 2003 · Liquid crystals have two main phases which are called the "nematic phase" and the "smectic phase." The nematic phase is the simplest of liquid crystal phases and is close to the liquid phase. The molecules float around as in a liquid phase, but are still ordered in their orientation. When the molecules are chiral* and in the nematic phase, …

WebLiquid crystals are special substances that are usually liquid, but that show certain properties of a solid crystal. A liquid crystal (LC) may flow like a liquid, but its molecules may be rotated in a crystal-like way. There are many different types of liquid crystal phases.
liquid crystal summary | Britannica
Webliquid crystal, Substance that flows like a liquid but maintains some of the ordered structure characteristic of a crystal. Some organic substances do not melt directly when heated but instead turn from a crystalline solid to a liquid crystalline state. When heated further, a true liquid is formed. Liquid crystals have unique properties.
