The PC-SAFT equation of state is used for thermodynamic modeling of poly(N-isopropylacrylamide) PNIPAAm in water and alcohols (methanol, ethanol, 1-propanol, and 2-propanol). For calculating the swelling behavior of cross-linked PNIPAAm gels, an additional contribution to the Helmholtz energy considering elastic forces is implemented and the resulting pressure difference in the gel is taken into account. The model is used to describe the gel-phase composition and the degree of swelling as a… CONTINUE READING
