Figure shows the tensile test results for the semicarbazide gel and urazole-potassium hydrogel. The test was conducted when the was in a swollen state. As can be seen, semicarbazide has a higher elastic modulus than the hydrogel, and it is also more brittle than the hydrogel. However, the hydrogel shows hyperplastic behavior, which is common for hydrogels. The results of each group are consistent with each other, which is a sign of good reproducibility and consistency of gel synthesis. The mechanical properties of the samples, such as Young's modulus and ultimate stress strain at break, are presented (Fig. ). The Young's modulus of the gel and hydrogel was 2.15 MPa and 0.91 MPa, respectively. For some application such as cartilage replacement, choice of hydrogels are limited because the modulus of most hydrogels is in the order of 0.1 MPa. Moreover, the gel and hydrogel ultimate stress is 0.499 MPa and 0.311 MPa, respectively and their strain at break is 25 % and 62.5% , respectively. It means that the hydrogel strain at break is almost 2.5 times the strain at break for the gel while its ultimate stress is 40% less than the gel. It means the although the hydrogel became ductile compared to gel but there is no drastic decrease in its strength.
