Synthetic hydrogels: Synthesis, novel trends, and applications

Hydrogels have been generated and explored for use in various applications. The main objective of this comprehensive review is to collate the fundamental concepts of hydrogels, and elaborate on knowledge gaps, and to provide a perspective on the future directions. This review includes details of constituent molecules (monomers, cross‐linkers, composite materials, etc.) and the methods used to prepare polymer networks. Moreover, the review...
