Biomechanical Performances of Networked Polyethylene Glycol Diacrylate: Effect of Photoinitiator Concentration, Temperature, and Incubation Time

Figure 4

Typical stress versus strain diagram derived from the tension test on the flat dumbbell-shaped PEGDA sample having variable PI concentrations (0.2% and 0.6%) and test temperatures (23°C and 37°C). The tension tests were performed on these samples immediately after the preparation of the specimen at 0.01 mm/sec. strain rate.
