For an interacting polymer, the partition function, from equation ( 3.10 ), can be written as. with Δ F =− kBT (ln Z − ln Z0) as the excess free energy due to interaction. For the excluded volume case of equation ( 3.5 ), this excess free energy is called the free energy of swelling. high gloss canvas nature https://paintthisart.com
