Comparing the Behavior of Single and Double Network Hydrogels UnderLarge Amplitude Oscillatory Shear (LAOS)

In this work, we used the LAOS technique to study the nonlinear response of a thermo-responsive κ-carrageenan/polyacrylamide double network (DN) system in comparison with its single network (SN)components. Our findings revealed a combination of strain stiffening and shear thickening nonlinearresponses. Furthermore, temperature dependency of the DN hydrogel owing to the conformationalchanges of the κ-carrageenan network at sufficiently elevated temperatures was used to investigatethe effect of temperature on the nonlinear behaviors
