摘要：

Swollen networks of charged macromolecular chains are widely used in the biomedical, pharmaceutical and related fields. The crosslinked structure of such systems defines their 'mesh size' and, therefore, their diffusive characteristics. A new model was developed to accurately describe the swelling behavior of charged polymeric networks. The model incorporates elastic, mixing and ionic contributions to the chemical potential. Changes in the equilibrium degree of swelling as a function of pH can be predicted.
