Diblock copolymer phase diagram as calculated using Mean-field Theory by Matsen and Bates, where fA is the Block fraction, χ is the Flory-Huggins Chi Parameter, and N is the length of the block; adapted from reference [1].

Structural phase diagrams are widely constructed as a means to summarize a wide range of structural behaviors. The simplest example of a structural phase diagram is for hard spheres, where structural behavior is a function of volume fraction only. Typically structural phase diagrams are plotted as a function of two dimensions. For example, in the study of Block Copolymer melts, structure is usually plotted as a function of temperature (or the Flory-Huggins Chi Parameter) and block fraction. Surfactant structural behavior is often plotted as a function of temperature and volume fraction (concentration).
