Abstract
We have investigated the effect of ionic and non – ionic surfactants on the structure and rheological properties of polyacrylamide hydrogels. With addition of ionic and non-ionic surfactants, just below and above their critical micellar concentration (CMC), there is a significant decrease in hydrogels mechanical strength as compared to the parent hydrogels alone. In oscillatory measurements, no frequency dependence is observed in the case of polyacrylamide hydrogels. However with the addition of surfactants, just below and above CMC, noticeable frequency dependence is observed.
