For a polymer material with liquid crystals , the liquid crystals are molecules shaped like rigid rods .. polymer. polymer. liquid crystals. liquid crystals. Just as logs being floated down a river tend to travel parallel to the direction of the river , liquid crystals have a preferential alignment with each other .. liquid crystals. liquid crystals. At high temperatures , this alignment is disrupted and the material is said to be in the isotropic state .. isotropic. isotrophy. At lower temperatures , the alignment will take place and the liquid crystals are said to be in the pneumatic state -LSB- Hoong.C.C -RSB- .. liquid crystals. liquid crystals.
