An innovative method for preparation of nanometal hydroxide superabsorbent hydrogel

Classification, processing and application of hydrogels: A review

“…Natural-hydrogels are usually prepared through the addition of some synthetic parts onto the natural substrates, e.g., graft copolymerization of vinyl monomers on polysaccharides. When the term ''hydrogel' 'is used without specifying its type, it truly means the conventional type of hydrogel [134]. The synthetic route for the production of most synthetic hydrogels is the free-radical multifunctional vinyl monomers.…”

Hydrogel: Preparation, characterization, and applications: A review

“…Hydrophilic gels that are usually referred to as hydrogels are networks of polymer chains that are sometimes found as colloidal gels in which water is the dispersion medium [1].…”

Polyaniline-poly(styrene sulfonate) conducting hydrogels reinforced by supramolecular nanofibers and used as drug carriers with electric-driven release

“…As reported previously, PANI-PSS conducting hydrogels can be employed as sensors of urease [12]. In order to obtain conductivity, addition of metal nanoparticles or graphene into the non-conducting hydrogels has also been reported [13,14]. Yet, a common problem of those conducting hydrogels is their low mechanical strength originating from the inherent low strength of hydrogels.…”
