    2014-9-25 · the gel is responsible for the high swelling ratio m rel,1 of polyelectrolyte first network, i.e., high n 21 ratio of the corresponding DN hydrogel, even at high cross-link densities ν e,1. For nonionic gels, since this term is zero, m rel,1 is close to unity, leading to low n 21 ratios and thus producing DN’s with a poor mechanical ...
