Oligo(amidoamine)s hydrogels with tunable gel properties.
A series of oligo(amidoamine)s (OAAs) that can be reversibly switched between sol and gel phases upon changes in pH and temperature have been synthesized and characterized. Their viscoelastic properties were significantly increased upon increasing the number of methylene groups, implying that viscoelasticity could clearly be tuned at the molecular level.
