Elastic, superporous hydrogel hybrids of polyacrylamide and sodium alginate.
A novel approach was developed to prepare a superporous hydrogel with superior mechanical and elastic properties. According to this method, a synthetic monomer was polymerized and crosslinked in the presence of a water-soluble alginate polymer. Later in the process, the alginate part of the synthesized hydrogel was treated with metal cations, which resulted in a hydrogel hybrid with an interpen...

KGaA, Weinheim 1 wileyonlinelibrary.com through the excitation of OH vibrations.[5] On the other hand, the mechanical properties of supramolecular gels typically suffer from the relatively weak noncovalent interactions among the constituent components.[6] This drawback also limits construction of free-standing objects from the luminescent gels.[7] Herein for ...
متن کاملEffects of Inorganic and Organic Additives on the Adsorption of Nonionic Polyacrylamide on Hematite
The effects of inorganic anions such as chloride, sulfate, and phosphate on the adsorption of non ionic polyacrylamide on hematite are studied. Adsorption of the polymer is reduced in all cases, with complete depression by phosphate. The relative eff«tiveness of these anions in reducing polymer adsorption in~ in the order chloride < sulfate < phosphate. a trend which corresponds to the relative...
متن کاملPolyacrylamide Hydrogel Properties for Horticultural Applications
Polyacrylamide (PAAm) hydrogels are commonly employed to ensure soil hydration in horticulture, but studies have shown that they have a minimal effect on crop life and quality. The reasons for this poor performance are not understood since the commercial hydrogels have not been adequately characterized. PAAm hydrogels were synthesized and their properties were measured along with those of comme...
