    2019-10-1 · Furthermore, the strength of the polyacrylamide hydrogel remains nearly constant even when a sample is cut with a crack prior to the tensile test, so long as the cut is shorter than a certain length, about 1 mm. That polyacrylamide hydrogel is cut-insensitive was noted in a previous paper focused on elastomers (Chen et al., 2017). It was also noted that this “certain length” is much larger than the mesh size of the hydrogel.
