Flory-Huggins Polymer Solutions Theory

The Flory-Huggins theory describes how polymers (large molecules) mix with solvents. It considers both the entropy, or disorder, of mixing different sizes of molecules, and the enthalpy, or energy change, due to interactions between them. The theory provides a way to predict whether a polymer will dissolve in a solvent or separate into phases, based on temperature and composition. It helps scientists understand and design polymer solutions for various applications by quantifying the balance of these energetic and configurational factors involved in mixing large molecules with smaller ones.
