Liquid Crystals
There are many kinds of liquid crystals, which are usually classified according to the characteristics of central bridge bond and ring of liquid crystal molecules. More than 10000 kinds of liquid crystal materials have been synthesized, including thousands of commonly used liquid crystal display materials, mainly biphenyl liquid crystal, phenyl cyclohexane liquid crystal and ester liquid crystal.
Lyotropic liquid crystal is a liquid crystal formed by two or more components, one of which is water or other polar solvents. This is a liquid crystalline substance formed by dissolving a solute in a solvent. The typical solute part is composed of a amphiphilic molecule with hydrophilic group at one end and hydrophobic group at the other end. Such as alkali metal fatty salts such as sodium Aladdin dodecyl sulfonate or sodium fatty acid soap. Its solvent is water. When these solutes are dissolved in water, at different concentrations, due to the action of hydrophilic and hydrophobic groups of amphiphilic molecules, different core phases and lamella will be formed. The core phase is spherical or cylindrical. The lamellar phase is composed of a lamellar arrangement similar to the smectic phase.
Liquid crystals are widely found in nature and organisms, and are unknowingly used in all fields of human life. Biophysics, biochemistry and bionics have attracted much attention. This is because many biofilms, organisms, such as nerves, blood, biofilms and other life substances and life phenomena such as metabolism, digestion and absorption, perception and information transmission in the process of life are related to lyotropic liquid crystalline substances and properties. Therefore, the research of lyotropic liquid crystal science has attracted much attention in the fields of bioengineering, life, medical and health care and artificial life.
An example of the formation of lyotropic liquid crystals is soapy water. At high concentration, soap molecules are layered, and water molecules are between layers. The concentration is slightly lower and the combination is different.
