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

Figure 1

Steps that are performed for finding the failure stress of a networked PEGDA. Step 1: 20% PEGDA in PBS mixture was added to the desired concentration of photoinitiator mixture and poured in the custom-made mold to cure the mixture in flat dumbbell shape. Step 2: the solution was exposed to UV light for 3 min. Step 3: the mold was disassembled by the careful removal of pins. Step 4: the silicon mold was flexed to easily extract the specimen without damaging the PEGDA specimen. Step 5: tension test on PEGDA samples at room and incubator (body) conditions. Step 6: analysis of load and displacement data for the calculation of the failure stress of the specimen.
