“…[26][27][28][29][30] Apart from these permanently cross-linked hydrogels, biomimetic chemistry and supramolecular assembly approaches can be utilized to prepare hydrogels with reversible chemical interactions. For example, mussel-inspired coordination chemistry can be employed to fabricate hydrogels with biomimetic dopamine groups containing catechols side chains that can reversibly complex ferric ions by tuning the pH, [31] while supramolecular hydrogels can be cross-linked by reversible noncovalent interactions, such as hydrogen-bond, metal-ligand coordination, electrostatic, hydrophobic, or host-guest interactions. [32][33][34] Alternatively, hydrogels can be fabricated as coatings or grafts on substrates to impart complementary properties such as improved strength and resistance to humid or harsh environments.…”

anthropogenic activities that have led to saline intrusion and contamination of the existing freshwater sources, making the current approaches for water treatment even more difficult and costly. [2][3][4] This, in combination with the continuously rising global water demand, results in a rather pessimistic prediction that an additional 2000 billion m 3 of freshwater supply will be required by 2030 to meet the global demand, assuming no gains on the current state of water-production capacity and efficiency. [5,6] As the existing freshwater sources are being depleted, there is a growing need for utilization of a broader range of water sources beyond the conventional ones, that is, brackish water, seawater, wastewater, and atmospheric moisture. [7] On top of that, there is a call for a greater focus on enhancing water security, particularly for the poor and vulnerable populations, as water scarcity is more critical in these geographical regions due to the lack of access to conventional infrastructure and power sources to produce clean water. [1,8,9] This, in addition to the increasing intensity and frequency of climate-related disasters, present unique demands, such as simple and off-grid operations, for water technologies (WTs) that can be deployed to manage the constraints imposed by these circumstances.

Marine mussels secret protein‐based adhesives, which enable them to anchor to various surfaces in a saline, intertidal zone. Mussel foot proteins (Mfps) contain a large abundance of a unique, catecholic amino acid, Dopa, in their protein sequences. Catechol offers robust and durable adhesion to various substrate surfaces and contributes to the curing of the adhesive plaques. In this article, we review the unique features and the key functionalities of Mfps, catechol chemistry, and strategies for preparing catechol‐functionalized polymers. Specifically, we reviewed recent findings on the contributions of various features of Mfps on interfacial binding, which include coacervate formation, surface drying properties, control of the oxidation state of catechol, among other features. We also summarized recent developments in designing advanced biomimetic materials including coacervate‐forming adhesives, mechanically improved nano‐ and micro‐composite adhesive hydrogels, as well as smart and self‐healing materials. Finally, we review the applications of catechol‐functionalized materials for the use as biomedical adhesives, therapeutic applications, and antifouling coatings. © 2016 The Authors.
