Polymer Chain Conformation Simulator

Interactive polymer physics simulator: a Brownian polymer chain of tunable length explores conformations under good, theta and poor solvent conditions while a molecular-weight histogram shows polydispersity (PDI) of the surrounding mixture.

A Brownian-dynamics model of a single polymer chain in solution, alongside a simulated batch of chains showing molecular-weight polydispersity.

⚙ Under the hood

Brownian-dynamics bead-spring polymer chain (Langevin dynamics) coiling in solution: switch solvent quality between good, theta and poor to watch the chain swell into a self-avoiding coil or collapse into a globule, with live radius of gyration and a fitted Flory exponent. A second panel simulates a batch of chains from a Flory most-probable distribution and computes Mn, Mw and the polydispersity index (PDI).
