Special Issue Information

Dear Colleagues,

Hydrogel is a three-dimensional network polymer formed by chemical and/or physical crosslinking in aqueous solution. Hydrogels are often highly absorbent and water-retaining so they can be used for adjusting humidity. Modified hydrogels have many other functions such as electrical property, mechanical property, temperature sensitive property, and so on. As a result, multifunctional hydrogel shows a significant and rapidly expanding role in many research areas. Hydrogels can be used as functional coatings, envelope structures, energy storage media, soil conservation, adsorption of harmful ions, and other applications in architecture, energy, and environment. Moreover, in the field of biomedicine and pharmacy, hydrogels can serve as drug carriers, wound healing dressing, tissue engineering scaffold, and other applications. Therefore, the design of novel hydrogels and their multifunctional applications present broad research prospects and need to be studied urgently.

This Special Issue fits into this framework and aims to gather research papers and review articles exploring novel multifunctional hydrogels and their application areas. The collected research topics include but are not limited to preparation and design of hydrogel, characterization, multifunctional evaluation, applications, numerical simulation, etc.

Central composite design (CCD) is a statistical experimental design technique that utilizes a combination of factorial and axial points to study the effects of multiple variables on a response. This study focused on optimizing hydrogel formulations for 3D printing using CCD. Three biopolymers were selected: sodium alginate (SA), gelatin (GEL), and carboxymethyl cellulose (CMC). The maximum and minimum concentrations of each polymer were established using a Google Scholar search, and CCD was employed to generate various combinations for hydrogel preparation. The hydrogels were characterized in accordance with their swelling degree (SD) in phosphate-buffered saline (PBS) and Dulbecco’s Modified Eagle Medium (DMEM), as well as their printability in 2D and 3D assays. The formulation consisting of 7.5% SA, 7.5% GEL, and 2.5% CMC exhibited the best swelling properties and exceptional printability, surpassing all other tested formulations. This study highlights the effectiveness of design of experiment methodologies in accelerating the development of optimized hydrogel formulations for various applications in 3D printing and suggests avenues for future research to explore their performance in specific biological contexts.
