Abstract
Shape-memory polyester-polyethylene oxide networks are synthesized through photopolymerization of hydrophobic poly[(D,L-lactide)-co-glycolide]tetraacrylate (PLGATA) and hydrophilic poly(ethylene glycol) dimethacrylate (PEGDMA). The materials can recover their original shape either quickly by heating stimulus or slowly upon immersion in water. The wettability, mechanical properties, and transition temperature of the polymer networks could be conveniently adjusted by variation of the compositions of PLGATA and PEGDMA. The hydrophilicity of PEGDMA could prospectively improve blood compatibility of polymer networks. They offer a high potential for biomedical applications such as smart implants, drug delivery systems, or medical devices. Copyright © 2010 John Wiley & Sons, Ltd.
