2. Overview First Discovered in 1890s while observing cholesterol Flow like liquids, but have a repeating crystalline pattern Reflect polarized light
3. Special Properties Most have 2 melting points Cholesterol Benzoate melts into a cloudy liquid at 145 C Then melts at 178 C into a clear liquid Discovered by Friedrich Reinitzner
4. More Properties Have strong dipoles and are easily polarized The atoms are arranged in a pattern along their axis
5. Real World Applications Electric fields can be used to change the colors of liquid crystals. Liquid crystal displays are in: Television screens (LCD display stands for liquid crystal display) Watch displays Cell phones Almost anything electronic with a screen.
6. More applications Soap Conducting foams Heat Sensitive cameras use liquid crystal screens that respond to heat.
7. 3 Different Types Depends on Temperature and Pressure Liquid Crystals only form under specific conditions
