Liquid crystal - Wikipedia
Liquid 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 a solid.

2024年12月3日 · 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.
A liquid crystal is a thermodynamic stable phase characterized by anisotropy of properties without the existence of a three-dimensional crystal lattice, generally lying in the temperature range between the solid and isotropic liquid phase, hence the term mesophase. Liquid crystal materials are unique in their properties and uses.

2018年10月1日 · 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.

2021年8月25日 · These substances, which possess long-range molecular order but still flow like liquids, are called liquid crystals. Liquid crystals are typically long, rigid molecules that can interact strongly with one another; they do not have isotropic structures, which are completely disordered, but rather have anisotropic structures, which exhibit ...

2023年5月10日 · What is Liquid Crystal? Liquid crystals, a particular type of state of matter referred as the fourth state of matter, or mesophase, is a separate intermediate phase that some compounds create between the solid (crystalline) and liquid (isotropic) phases. These substances exhibit both solid and liquid-like characteristics.
11.8 Liquid Crystals - ChemicalAid
Many substances exhibit phases that have properties intermediate between those of a crystalline solid and a normal liquid. These substances, which possess long-range molecular order but still flow like liquids, are called liquid crystals.
The liquid crystal state is a distinct phase of matter observed between the crystalline (solid) and isotropic (liquid) states. There are many types of liquid crystal states, depending upon the amount of order in the material. This section will explain the phase behavior of liquid crystal materials.
Liquid crystalline properties are exhibited by several different types of systems. In addition to certain classes of organic molecules, micellar solu-tions of surfactants, main and side chain polymers, and a large number of biological systems are known to be liquid crystalline.

Liquid crystal (LC) is an intermediate state between crystal and liquid showing the properties of both. For example, liquid crystal may flow like a liquid but its molecules may have a specific crystal-like orientation.
