Stimuli-responsive hydrogels from polyampholytes have recently attracted great interest in various fields of applications due to their tunable rheological properties. In the current work, we study the influence of pH and ionic strength on the associative character of several types of polyampholytes and the resulting nanostructure of the hydrogels. By means of small-angle neutron scattering, we reveal the strong influence of the charge asymmetry and density on the network architecture. The dynamical processes in the gels are investigated using rotational dynamic light scattering.
