In this feature article, we critically review the physical properties of porous hydrogels and
their production methods. Our main focus is nondense hydrogels that have physical pores …

Superabsorbent polymers are a class of polymeric materials that have the ability to absorb
and retain a large amount of water and aqueous solutions. They are composed of three …

Abstract A new FG-g-AM-cl-MBA-MnO 2 hydrogel has been synthesised via a free radical
cross-linking reaction using fenugreek gum containing macromolecular galactomannan …

Superabsorbent polymer (SAP) materials are hydrophilic networks that can absorb and
retain huge amounts of WATER or aqueous solutions. They can uptake WATER as high as …

Polyvinylpyrrolidone (commonly known as povidone or PVP) rapidly dissolves in water. This
significantly hinders its use in sustained release formulations developed for the biomedical …

Graft copolymerization of mixtures of acrylic acid (AA) and acrylamide (AAm) onto chitosan
was carried out by using potassium persulfate (KPS) as a free radical initiator in the …

Polyaspartic acid (PAsp) resin was synthesized by polysuccinimide (PSI), through chemical
cross-linking using the cross-linking agent (diamine). The effects of reaction variables, such …

High water production is a common problem in mature oil reservoirs. Gel-based treatments
have been widely used as blocking agents to control water production in heterogeneous …

Superabsorbent polymers (SAPs) have proven to be a very promising admixture which can
positively influence various properties of cement-based materials. SAP samples intended for …

Hydrogels are polymeric materials which can swell in water and retain a significant fraction
of water within their structure without dissolving in water. Swelling rate is one of the most …
