Figure 3. Six different hydrogels (a-f) were prepared using 5 or 10% of polyvinyl alcohol (PVA) with 10, 20, or 40% polyethylene glycol (PEG). Hydrogels (a, b, and c) made with 5% PVA were so weak, regardless of PEG concentration, that they were easily torn by hand. Hydrogels (d, e, and f) containing 10% PVA did not tear as easily as hydrogels made with 5% PVA, but when the concentration of PEG reached 40%, they became too hard and were easily broken. The Young’s modulus, tensile strength, and percent elongation of the hydrogel were measured by a texture analyzer. (g) Representative stressstrain curve of hydrogels prepared with different PEG concentrations.
Figure 4. (a) Average percent elongation and tensile strength and (b) gel fraction and swelling ratio depended on the PEG concentration.
