    2019-4-3 · The wet and soft hydrogel materials are based on cross-linked hydrophilic polymers. Some hydrogel materials are cross-linked polyelectrolytes with ionic groups on the macromolecular chains. Therefore, the polyelectrolyte gels possess unique physical and chemical properties [Tanaka 1982, Ilmain 1991, Okuzaki 1995, Woessener 1970, Osada 1992].
