A smaller fraction of tough hydrogels has been applied as soft actuators, as anti-freezing gels, fire-resisting materials, as well as in information storage. Cui et al. reported a micellization-driven double network hydrogel based on Alg-Li + /P(AAm-stat-SMA)-SDS. The authors argued that the ideal fire-resistant hydrogel required mechanical toughness, self-healing and water-retaining properties and hence, made a case study with their materials. When the LiCl content in the hydrogels was increased (> 4.0 M), the ratio of ion-bound water to free water increased, leading to enhanced water retaining properties of the hydrogels. This came, however, at the expense of the self-healing behavior, which passed a maximum of 35% at 1.0 M. Altogether, a 2 mm thick hydrogel was capable of resisting a high temperature flame spray for 45 s.
