Special Issue Information

Dear Colleagues,

Hydrogels have garnered significant attention due to their ultra-high softness and deformable properties. These advantages have highlighted their potential as a biointerface or matrix for bioplatforms. However, conventional polymeric hydrogels often suffer from mechanical weakness and a lack of intrinsic functionality, limiting their potential applications. To address this issue, researchers have explored various approaches, including modifying the chemical structures of the backbone polymer of the hydrogel or utilizing multiple backbone polymer networks, to impart additional functions or enhance their inherent characteristics.

Another promising approach involves incorporating various types of auxiliary filler materials into bare hydrogels. These hydrogel composites obtain additional features from the filler materials while retaining their orginial advantageous characteristics. Examples include stimul-responsive behavior, theranostic functions, and electrochemical properties, all of which hold great promise for various biomedical applications. Currently, extensive efforts are underway to develop new hydrogel formulations, implement integrated hydrogel composites, and expand their applications.

This Special Issue is dedicated to showcasing the recent developments in both bare hydrogels and hydrogel composites with high performance and multifunctionality. Furthermore, we welcome contributions that highlight application examples of hydrogel-based systems tailored to specific fields or that pave the way for new fields of study.

Water is one of the fundamental resources for the existence of humans and the environment. Throughout time, due to urbanization, expanding population, increased agricultural production, and intense industrialization, significant pollution with persistent contaminants has been noted, placing the water quality in danger. As a consequence, different procedures and various technologies have been tested and used in order to ensure that water sources are safe for use. The adsorption process is often considered for wastewater treatment due to its straightforward design, low investment cost, availability, avoidance of additional chemicals, lack of undesirable byproducts, and demonstrated significant efficacious potential for treating and eliminating organic contaminants. To accomplish its application, the need to develop innovative materials has become an essential goal. In this context, an overview of recent advances in hydrogels based on chitosan and nanocomposites and their application for the depollution of wastewater contaminated with dyes is reported herein. The present review focuses on (i) the challenges raised by the synthesis process and characterization of the different hydrogels; (ii) the discussion of the impact of the main parameters affecting the adsorption process; (iii) the understanding of the adsorption isotherms, kinetics, and thermodynamic behavior; and (iv) the examination of the possibility of recycling and reusing the hydrogels.
