Poly (ethylene glycol) (PEG) hydrogels are widely studied and frequently used biomaterials [1,2].A significant challenge to hydrogels is to control their shape and size.Our research interests were the design of novel microscale hybrid hydrogel networks under bio-friendly conditions.In this work,hydrogels were fabricated by free-radical redox polymerization with PEG dimethacrylate (PEGDMA) (200 g/mol) and 2-hydroxyethyl methaerylate (HEMA) using ammonium persulfate (APS) and N,N,N,N-tetramethylethylene diamine (TEMED) as initiators and N,N-methylene bisacrylamide (BIS) as cross-linker (Fig.1).Carboxylated carbon nanotubes (CNTs) were also added to the copolymer system to improve the swelling and mechanical properties.
