General description

Surface grafted polyethylene glycol (PEG) prevents protein absorption. Poly (ethylene glycol) methyl ether methacrylate (m-PEGMA) is often used to create PEG modified surfaces. Studies report the grafting of m-PEGMA on poly ether urethane surface by ozone induced polymerization, on emeraldine film by UV induced copolymerization.

Application

The methacrylate end-group allows for this material to be further polymerized.
