文摘

Solutions of Poloxamer 407 and poly (ethylene glycol) diacrylate were investigated. The solutions show a physical gelling in a wide concentration window. Photocuring of poly (ethylene glycol) diacrylate is accelerated by Poloxamer 407. Stiffness and water content of cured hydrogels can be adjusted.
