Web3. The heat of mixing of polymer and solvent, which may be positive, negative, or zero. Usually it is slightly positive, opposing mixing. The FloryRehner equation may be written v2 13 2 - [ln (1 - v2 ) + v2 + c1v2 ] = V1 n v2 - 2 (9.92) where v2 is the volume fraction of polymer in the swollen mass, V1 is the molar volume of the solvent, and c1 ... http://www.matsumoto.nuem.nagoya-u.ac.jp/jascome/denshi-journal/17/JA1710.pdf

WebJul 30, 2024 · In this work, the Flory–Rehner equation is revisited to evidence the dependency of the interaction parameter on both polymer volume fraction and temperature. Such an analysis to estimate the true functionality of the interaction parameter is based on experimental data reported in the literature for the swelling behavior of NIPA hydrogels … In polymer science Flory–Rehner equation is an equation that describes the mixing of polymer and liquid molecules as predicted by the equilibrium swelling theory of Flory and Rehner. It describes the equilibrium swelling of a lightly crosslinked polymer in terms of crosslink density and the quality of the solvent. The … See more The Flory–Rehner theory gives the change of free energy upon swelling of the polymer gel similar to the Flory–Huggins solution theory: The theory … See more • Flory, Paul; Rehner, John (1943).
