- Abstract
Hydrogels have been widely used for biomedical and tissue engineering applications, and there are a lot of both synthetic and natural systems used for these purposes. In this study, we described the synthesis, characterization and properties of a novel hybrid PEG-based hydrogel in situ polymerization. The hybrid hydrogel was prepared by free-radical redox polymerization using TEMED/APS as initiators and N,N'- methylenebisacrylamide (BIS) as cross-linker at 60 °C. The physicochemical properties of hybrid hydrogel were characterized by FT IR spectroscopy and scanning electron microscopy (SEM), while swelling kinetics and gel content were calculated. The results indicated swelling degree in distilled water could come to a maximum of 537% with 0.3 wt% CNTs. SEM images showed the micron pore size of hydrogels could be adjusted by changing the cross-linker mass from 2 wt% to 10 wt%. So, the obtained hydrogels with appropriate crosslinkage would be exploited as biomedical applications, such as tissue engineering and three dimensional tissue scaffolds.
