“…Furthermore, the IPN hydrogels are less cytotoxic than PVA hydrogels, however, the increased PVA/PNIPAAM ratio results in lower cytocompatibility. Wei et al synthesized Salecan (a microbial polysaccharide) and PNIPAM based thermosensitive semi‐IPNs. The synthesized semi‐IPNs have good swelling capacities at room temperature as well as excellent thermosensitive properties, having rapid response rates to temperature changes.…”

Gum polysaccharides are one of the most abundant bio‐based polymers. They are generally derived from plants as exudates or from microorganisms and have diverse applications in many industries, especially in the food industries where they are used as emulsifiers and thickeners. In their natural form, gum polysaccharides have poor mechanical and physical properties; therefore, they are frequently modified with various synthetic monomers such as acrylamide and acrylic acid using graft copolymerization. Graft copolymerization is one of the most trusted and widely used synthetic methods for the modification of gum polysaccharides. Gum polysaccharides modified in this way have improved mechanical and physicochemical properties. Furthermore, gum polysaccharides contain a variety of functional groups, for example, carboxylic acid and hydroxyl groups; therefore, they have been used extensively as adsorbents for the removal of different impurities from wastewater such as toxic heavy metal cations and synthetic dyes. Here, the chemical and physical properties of gum polysaccharides, different methods of graft copolymerization, and the use of graft copolymer gum‐polysaccharide‐based hydrogels are reviewed in detail for the removal of toxic heavy metal cations and synthetic dyes from aqueous solutions.

“…[1][2][3][4] Owing to the excellent biocompatibility and stimuli-responsiveness, hydrogels have potential applications in cosmetics, wound healing, artificial tissues, drug delivery and antifouling. 11 To address this, various strategies and concepts have been developed to make mechanically robust hydrogels including interpenetrating and double networks, 12,13 slide ring polymer hydrogels, 14 topological hydrogels, 15 ionically cross-linked copolymers, 16,17 nanocomposite polymer hydrogels, [18][19][20][21][22][23] macromolecular microsphere composite (MMC) hydrogels hydrogels 24 etc. 11 To address this, various strategies and concepts have been developed to make mechanically robust hydrogels including interpenetrating and double networks, 12,13 slide ring polymer hydrogels, 14 topological hydrogels, 15 ionically cross-linked copolymers, 16,17 nanocomposite polymer hydrogels, [18][19][20][21][22][23] macromolecular microsphere composite (MMC) hydrogels hydrogels 24 etc.…”

We reported a series of tough nanocomposite hydrogels with good antifouling properties based on quaternized hybranched polyethylenimine (HPEI) nanoparticles. The quaternized HPEI nanoparticles acted as both cross-linkers to produce tough hydrogels and antibacterial agents to prevent fouling attachments. Compared with the polymer hydrogel, these nanocomposite hydrogels exhibited significantly improved mechanical properties. The mechanical strength of the nanocomposite hydrogels had a strong dependence with proportion of the quaternized HPEI nanoparticles. Furthermore, the anti-algae /bacterial assay indicated the nanocomposite hydrogels showed better antimicrobial and anti-algae performances due to the broad spectrum antimicrobial activity of Quaternary Ammonium Salts (QAS) functional groups.

“…While the temperature was below the VPTT, the hydrophilic amide groups form hydrogen bonds with water molecules, and hydrophilic PNIPAM shells swell with water to increase hydrodynamic volumes. As the temperature was above the VPTT, hydrogen bond was destroyed and water was expelled due to hydrophobic PNIPAM shells shrink dramatically, and their hydrodynamic size will decrease greatly [28][29][30].…”

Fe 3 O 4 /poly(N-isopropylacrylamide-methacrylic acid-N,N 0 -methylenebisacrylamide)(Fe 3 O 4 /P(NIPAM-MAA-MBA)) peapod-like nanochains have been successfully synthesized by magnetic field-induced precipitation polymerization. Fe 3 O 4 microspheres modified with vinyl groups can be arranged with the direction of the external magnetic field in a line and linked permanently via P(NIPAM-MAA-MBA) coating during precipitation polymerization. The properties of 1D Fe 3 O 4 / P(NIPAM-MAA-MBA) were characterized by transmission electron microscopy, X-ray diffraction, thermogravimetric analysis (TGA), vibrating sample magnetometry, X-ray photoelectron spectroscopy, and UV-Vis spectrophotometer. Magnetic measurement revealed that these 1D peapod-like nanochains showed highly magnetic sensitivity. The thermaland pH-response of 1D magnetic Fe 3 O 4 /P(NIPAM-MAA-MBA) nanochains was investigated by the temperature/pH dependence of hydrodynamic radius of Fe 3 O 4 /P(NIPAM-MAA-MBA) microspheres. The release behavior of phenolphthalein from 1D magnetic Fe 3 O 4 /P(NIPAM-MAA-MBA) nanochains could be effectively controlled by changing the temperature/pH values.
