General description
PCL-PEG-PCL diacrylate, average Mn 100-1000-100, is a functionalized, amphiphilic triblock copolymer composed of a central hydrophilic, biocompatible poly(ethylene glycol) (PEG) block and two terminal hydrophobic, biodegradable poly(caprolactone) (PCL) blocks. PCL-PEG-PCL diacrylate can be crosslinked via free radical polymerization and/or photopolymerization to form a crosslinked hydrogel network. Hydrolysis of the esters of the PCL blocks permits degradation of the crosslinked networks.
Application
- Tissue engineering
- 3D printing
- Drug delivery
Features and Benefits
- PCL-PEG-PCL triblock copolymer
