Abstract
This study describes the in-situ gelation kinetics of polyacrylamide PAM and PAM-Clay networks precursory reactional mixtures and the rheological properties of the resulting hydrogels. Elastic G’ and loss G” moduli measurements via oscillatory shear in dynamic rheology and the structural parameters calculation of the networks using the rubber elasticity theory enabled us to apprehend the relationship between the hydrogels structure and the composition of their precursory mixtures: (i) the presence of the Clay and its absence, (ii) its content and its homoionized or organo-modified nature and (iii) the presence of the cross-linking agent and its absence.
