Clearly, the DN gel exhibits quite significant viscous properties (due to hydrazone cross-links), while it still maintains the elastic character as well, resulting in a stable structure in time (due to DA cross-links). 3.4 Tunable Stress Relaxation and Viscoelastic Properties Stress relaxation is an important feature of viscoelastic materials to investigate as they display time-dependent mechanical response.
