5 Questions
What causes the contrasting textures in liquid crystals?
The contrasting textures in liquid crystals arise due to molecules within one area of material (domain) being oriented in the same direction, but different areas having different orientations.
What are the properties of liquid crystals?
Liquid crystals have properties between those of conventional liquids and solid crystals. They can flow like a liquid, but their molecules may be oriented in a crystal-like way.
What are thermotropic and lyotropic liquid crystals mostly made of?
Thermotropic and lyotropic liquid crystals consist mostly of organic molecules, although a few minerals are also known.
How many types of liquid crystals are there?
There are three main types of liquid crystals: thermotropic, lyotropic, and metallotropic.
When do thermotropic liquid crystals exhibit a phase transition?
Thermotropic liquid crystals exhibit a phase transition into the liquid crystal phase as temperature changes.
