Flory-Huggins solution theory

Flory-Huggins solution theory explains how different molecules mix or separate in a solution. It considers both the entropy, which favors mixing due to increased disorder, and the enthalpy, which depends on how molecules interact. The theory uses a mathematical parameter called the interaction parameter to predict whether components will mix uniformly or separate into distinct phases. It is particularly useful for understanding polymer solutions, helping predict solubility and phase behavior based on molecular size, interactions, and temperature, thus aiding in designing materials and processes involving mixtures at the molecular level.
