Swelling Behavior of Poly(Acrylamide) Nanoclay Composite Hydrogels

Abstract:

A series of nanocomposite (NC) hydrogels were synthesized by in-situ polymerization of acrylamide (AAm) monomer using laponite XLS clay as a crosslinker. This paper focused on water absorbency of the NC hydrogels with various clay contents, at various pH values and ionic strengths. The influence of pH value on swelling behaviors showed that a maximum swelling ratio was observed at pH 11. The swelling abilities of the NC composites decreased in saline solution strength. Heat treatment of NC hydrogels improved the swelling capacity of the hydrogels.
