Abstract:

Free energy of a single polymer chain in polymer solutions is critical for the derivation and understanding of the scaling law between the polymer size and its degree of polymerization. This work provides a novel derivation of the single-chain free energy based on the Flory lattice model.

Key words: Single chain, Polymer solution, Scaling law, Free energy
