2018/5/8· This is the mechanism that makes liquid crystal thermometers work — you see red when the liquid crystals in the thermometer are cool, then yellow, green, and blue as they are warmed. The most important use of liquid crystals is in displays because the molecules of a liquid crystal can control the amount, color, and direction of vibration of the light that passes through them.

Classifiions of Liquid Crystals

Liquid crystals are a unique state of matter, between solid (crystalline) and liquid (isotropic) phases some compounds form a distinct, different intermediate phase, sometimes referred to as the “fourth state of matter” or “mesophase”. These compounds display properties of both solid and liquid.

Hence liquid crystals are not as disordered as a liquid because the molecules have some degree of alignment. Most substances that exhibit the properties of liquid crystals consist of long, rigid rod- or disk-shaped molecules that are easily polarizable and can orient themselves in one of three different ways, as shown in Figure \(\PageIndex{2}\).

How Do Crystals Form? | Science Trends

The proof-of-concept calculations presented in this work show indeed the formation of crystals consisting of several different phases. First is the formation of liquid-like droplets. These are not simple but consist of alternating spherical layers of high and low density “shells” – a phenomenon common in confined liquids but often neglected in simpler approaches (like CNT).

Thermochromic Liquid Crystal - an overview | …

Thermochromic liquid crystals mainly include cholesteric liquid crystal and cyano biphenyl liquid crystal. Organic thermochromic compounds can be further divided into two egories. One group consists of single component (such as Schiff bases, spiro and double anthracene ketone chemicals), and its colour-changed properties are ascribed to changes in the composition or structure after heating.

Materials Science and Engineering: Liquid Crystals | …

Liquid crystals can be be manipulated by heat and cold, and electric, magnetic or mechanical forces. There are two kinds of liquid crystals: those that undergo phase changes due to temperature (themotropics) and those that undergo phase changes due to the density of a liquid, such as water (lyotropics). Liquid crystals are everywhere.
