“…Starch-based hydrogels were prepared via the simultaneous formation of magnetic iron oxide nanoparticles and in situ radical solution polymerization of poly(acrylicacid-co-acrylamide) (P(AA-co-AM)) grafted onto starch backbones in the presence of graphene oxide (GO) nano sheets, which exhibited pH-responsiveness and magnetic characteristic on swelling/de-swelling pulsatile behaviors [ 10 ]. GO/polyacrylamide/aluminum ion cross-linked carboxymethyl hemicellulose nanocomposite hydrogels (GO/PAM/Al 3+ -CMH) were produced by the two-step process, which possessed the high strength and great elasticity [ 11 ]. The PAM/gelatin/polyvinyl alcohol (PVA) hydrogel with triple-network was prepared by a simple one-pot method, consisting of copolymerization, cooling and freezing/thawing [ 12 ], which displayed superior mechanical properties.…”

Introducing multifunctional groups and inorganic material imparts xylan-based hydrogels with excellent properties, such as responsiveness to pH, temperature, light, and external magnetic field. In this work, a composite hydrogel was synthesized by introducing acid treated carbon nanotubes (AT-CNTs) into the maleic anhydride modified xylan grafted with poly(N-isopropylacrylamide) (MAX-g-PNIPAM) hydrogels network. It was found that the addition of AT-CNTs affected the MAX-g-PNIPAM hydrogel structure, the swelling ratio and mechanical properties, and imparted the hydrogel with new properties of electrical conductivity and near infrared region (NIR) photothermal conversion. AT-CNTs could reinforce the mechanical properties of MAX-g-PNIPAM hydrogels, being up to 83 kPa for the compressive strength when the amount was 11 wt %, which was eight times than that of PNIPAM hydrogel and four times than that of MAX-g-PNIPAM hydrogel. The electroconductibility was enhanced by the increase of AT-CNTs amounts. Meanwhile, the composite hydrogel also exhibited multiple shape memory and NIR photothermal conversion properties, and water temperature was increased from 26 °C to 56 °C within 8 min under the NIR irradiation. Thus, the AT-CNTs reinforced MAX-g-PNIPAM hydrogel possessed promising multifunctional properties, which offered many potential applications in the fields of biosensors, thermal-arrest technology, and drug-controlled release.

“…However, it is known that non‐covalent bonds, such as metal coordination and hydrogen bonds, are dynamically reversible. These dynamically reversible bonds could endow a material with thermoplastic and self‐healing properties . Therefore, the self‐healing properties of the PAA‐Fe 3+ /Gelatin/PVA triple‐network hydrogels were investigated, as displayed in Fig.…”

Hydrogels with good mechanical and self‐healing properties are of great importance for various applications. Poly(acrylic acid)–Fe3+/gelatin/poly(vinyl alcohol) (PAA‐Fe3+/Gelatin/PVA) triple‐network supramolecular hydrogels were synthesized by a simple one‐pot method of copolymerization, cooling and freezing/thawing. The PAA‐Fe3+/Gelatin/PVA triple‐network hydrogels exhibit superior toughness, strength and recovery capacity compared to single‐ and double‐network hydrogels. The mechanical properties of the synthesized hydrogels could be tailored by adjusting the compositions. The PAA‐Fe3+/Gelatin/PVA triple‐network hydrogel with 0.20 mmol Fe3+, 3% gelatin and 15% PVA could achieve good mechanical properties, the tensile strength and elongation at break being 239.6 kPa and 12.8 mm mm−1, respectively, and the compression strength reaching 16.7 MPa under a deformation of about 91.5%. The synthesized PAA‐Fe3+/Gelatin/PVA triple‐network hydrogels have good self‐healing properties owing to metal coordination between Fe3+ and carboxylic groups, hydrogen bonding between the gelatin chains and hydrogen bonding between the PVA chains. Healed PAA‐Fe3+(0.20)/Gelatin3%/PVA15% triple‐network hydrogels sustain a tensile strength of up to 231.4 kPa, which is around 96.6% of the tensile strength of the original samples. Therefore, the synthesized triple‐network supramolecular hydrogels would provide a new strategy for gel research and expand the potential for their application. © 2019 Society of Chemical Industry

“…Over the past few decades, there has been an explosive interest in developing self-healing materials because of their built-in ability to repair physical damage, effectively avoiding catastrophic failure and extending the working life 1 , 2 . According to the healing mechanisms, self-healing materials can be divided into types of extrinsic self-healing and intrinsic self-healing 3 . The former achieve their self-healing process through releasing healing agents from capsules.…”

A self-healing polybenzoxazine is synthesized solely based on dynamic ester bonds. For this purpose, an anhydride (succinic anhydride) was added into bisphenol F derived benzoxazine monomer before thermocuring. Owing to the transesterification of newly formed ester bonds, the thermoset network behaves as a thermoplastic at 140 °C in the presence of Zn (Ac)2, and shows self-healing properties even after multiple damage-healing cycles. Furthermore, kinetics study indicates that the transesterification is a first-order reaction and the activation energy is about 135.4 kJ/mol. This study proposes a facile and economical way to prepare self-healing polybenzoxazine. It has promising applications in coating, adhesive, and other smart materials that rely on structurally dynamic polymers.
