Overview Abstract Over the past few years, there has been a great deal of interest in the development of hydrogel materials with tunable structural, mechanical, and rheological properties, which exhibit rapid and autonomous self-healing and self-recovery for utilization in a broad range of applications, from soft robotics to tissue engineering.
They armed the hydrogel network with flexible-pendant side chains carrying an optimal balance of hydrophilic and hydrophobic moieties that allows the side chains to mediate hydrogen bonds in acid conditions across the hydrogel interfaces rapid self-healing hydrogels minimal steric hindrance and hydrophobic collapse.
The material has numerous potential applications, including medical sutures, targeted drug delivery, industrial sealants and self-healing plastics, a team of UC San Diego Jacobs School of Engineering researchers reported March 5 in the online Early Edition of the Proceedings of the National Academy of Sciences.
Hydrogels are made of linked chains of polymer molecules that form a flexible, jello-like material similar to soft-tissues.

Additionally, the rapidity of self-healing in response to acids makes the material a promising candidate to seal leakages from containers containing corrosive acids. To test this theory, her lab cut a hole in the bottom of a plastic container, "healed" it by sealing the hole with the hydrogel and rapid self-healing hydrogels that it prevented any leakage of acid through the hole.
