Poly(2-hydroxyethyl methacrylate), commonly known as PHEMA, is a synthetic hydrophilic polymer formed from methacrylate monomers bearing hydroxyl side groups. This material is valued in biomedical applications for its hydrogel-forming capability, biocompatibility, and tunable water content, making it particularly suited for implant coatings, soft-tissue contact devices, and controlled-release matrices. Engineers select PHEMA over alternative polymers when applications demand a balance of mechanical stability with moisture absorption and biological tolerance.
