Abstract

No theories have been able to predict the swelling behavior of polyelectrolyte gels over a wide range of ionic strength and the entire range of ionization. Based on recent theories of counter-ion condensation, polyelectrolyte interactions, and nn-Gaussian chain statistics, we have developed a more comprehensive model which predicts the swelling behavior of polyelectrolyte gels over a wide experimental conditions. To compare the theoretical predictions with the experimental results, we matched the predictions with the swelling ratio results for gels swollen in deionized water. We can see that the predictions are in reasonably good agreement with the experimental results. Noticing that the swelling ration in DI water is about 10 times higher than the swelling ration of the same samples in 0.1538 M NaCl solution, the agreement between theory and experimental results is quite impressive.
