Poly(ethylene glycol) dimethacrylate is widely used in the production of hydrogels due to its ability to form cross-linked networks when polymerized. These hydrogels are employed in biomedical applications such as drug delivery systems, where they provide controlled release of therapeutic agents. Additionally, it is utilized in the fabrication of contact lenses and other ophthalmic devices, offering high water content and biocompatibility. In tissue engineering, it serves as a scaffold material to support cell growth and tissue regeneration. The chemical is also incorporated into adhesives and coatings, enhancing their flexibility and durability. Furthermore, it finds application in the development of sensors and actuators in smart materials due to its responsive properties to environmental stimuli.
