“…In addition, the fitted removal efficiency of Gel-E for MB reached 85.3248 mg/g, whereas for the BPA system, the calculated removal efficiency showed value of 20.7297 mg/g. It should be noted that from previous reports, the removal efficiencies of MB from different composite materials, including sandwiched Fe 3 O 4 /carboxylate graphene oxide nanostructure, polydopamine sheathed electrospun nanofibers, and diamond based core–shell nanocomposites, showed the value range of 34–40 mg/g. − In addition, some two-component supramolecular gels based on glutamic acid component and graphene oxide hydrogels demonstrated the maximum removal values of 16.898 and 334.448 mg/g for MB removal. , Thus, present obtained composite gel materials exhibited excellent removal capacities for MB molecules. Moreover, durability and regeneration of absorbent materials seemed very important in real industrial application.…”

The excellent physical and chemical properties of cyclodextrin polymer (poly-CD)/azobenzene-modified polyacrylic acid (PAA-Azo) binary composite hydrogels have been designed and prepared. The prepared hydrogels were subjected to a variety of characterizations, including scanning electron microscopy, ultraviolet spectroscopy, circular dichroism spectroscopy, infrared spectroscopy, rheological properties, and specific surface area tests. It was found that the obtained hydrogels have the cross-linked three-dimensional porous network nanostructures, and the formed composite poly-CD/PAA-Azo hydrogel can basically be shear thinned and have good recovery performance. A process of gel–sol transition can occur when the gel has a stimulatory response under UV light irradiation. In addition, such excellent properties of hydrogels exhibit different mechanisms in the adsorption of organic molecules that are harmful to the environment, such as bisphenol A (BPA) and methylene blue (MB). The polymeric hydrogel serves as novel adsorbent agents to adsorb BPA via host–guest interaction and anchor MB via electrostatic interaction and hydrogen bonding.
