Abstract

A new poly(ethylene oxide) based biomaterial has been synthesized by co-crosslinking linear poly(ethylene oxide) (PEO) with tetraethylene glycol (TEG) in aqueous solution using electron beam radiation. This process results in hydrogels with variable concentrations of hydroxyl groups, tunable by adjusting the concentration of TEG in solution. FTIR analysis of these gels shows no changes in chemical composition on crosslinking.
