They consist of long, discrete molecules that meltto a viscous liquid at the processing temperature, typically 500” to 700” F (260° to 3710 C), and, after forming, are cooled to an amorphous, semicrystalline, or crystalline solid. The degree of crystallinity has a strong ef-
Chapter 2 Polymer Crystallization – Literature review
vtechworks.lib.vt.eduFrom thermodynamic considerations alone, a crystal is in a lower free energy state than the liquid when the temperature is below the melting point (Te ∞) for a large crystal of a very high molecular weight polymer. Figure 2.1 shows schematically the changes in the Gibbs free energy of liquid and a crystal with temperature. The necessary (but not
Introduction to Liquid Crystals
uh.eduLiquid Crystal Phases The liquid crystal state is a distinct phase of matter observed between the crystalline (solid) and isotropic (liquid) states. There are many types of liquid crystal states, depending upon the amount of order in the material. This section will explain the phase behavior of liquid crystal materials. Nematic Phases
