Summary: Spiropyran-containing hydrogels with sole mechanochromic properties were synthesized by incorporating spiropyran bearing polymer beads in poly(AM-co-MA/DMSP3) hydrogels. The resulting hydrogel showed high mechanical properties and a good self-recovery feature. It exhibited reversible color changes under force-induced deformation and relaxed recovery states, making it a potential candidate for outdoor strain sensors.

Summary: Multi-bond network (MBN) hydrogels with hierarchical dynamic bonds exhibit super-tough mechanical properties due to the dissociation of UPy dimers and the introduction of ionic bonds, allowing for excellent self-recovery ability. The high dimerization constant of UPy motifs contributes to the self-recovery ability of the MBN hydrogels, enabling re-association of UPy dimers and ionic bonds after being dissociated.

Summary: Hydrogels with stimuli-responsive volume changing abilities are being used in soft actuators and robots, but traditional tough hydrogels cannot satisfy both high toughness and high stimuli responsiveness. This study introduces a material design that combines responsive and tough components in a single hydrogel network, allowing for the synergistic realization of high toughness and actuation performance.

Summary: This study proposes a strategy for developing strong and tough hydrogels by enhancing the interaction between the side groups on polymeric chains and the dispersing medium. Hydrogels are fabricated with a polyacrylamide-alginate double network in a choline chloride saturated solution. The hydrogels exhibit high transparency, toughness, fatigue resistance, self-healing, adhesion, as well as water retention, anti-freezing, and conductivity due to the strengthened hydrogen bonds within the dispersing medium. This research may inspire the development of tough and conductive gels for applications in e-skins, soft robots, and intelligent devices.

Summary: Self-healing, thermoresponsive hydrogels with a triple network were synthesized by copolymerizing N-isopropyl acryl amide (NiPAAm) with polyvinyl alkohol (PVA) functionalized with methacrylic acid and N,N'-methylene bis(acryl amide) crosslinker in the presence of low amounts of tannic acid (TA). The hydrogels showed good thermal responsiveness, thixotropic properties and enhanced dimensional robustness.

Summary: This study presents highly stretchable and tough hydrogels with controlled light-triggered photo-degradation for the first time. The hydrogels are formed by a double-network structure with covalently and ionically crosslinked subnetworks. By using a novel crosslinker, the mechanical properties of the hydrogel were not affected. The hydrogels show potential applications in health, electronics, and energy due to their excellent mechanical properties and controlled degradation.

Summary: In this study, cerium-initiated graft polymerization was used to fabricate hydrogels with high resilience, high tensile strength, and toughness, using cellulose-derived nanomaterials. By adjusting the ratios of cellulose nanocrystals and cellulose nanofibrils, the physical behavior of the composite material can be finely tuned. Furthermore, the hydrogels showed excellent biocompatibility and supported increased cell viability and proliferation compared to hydrogels made only from acrylamide.

Summary: This study proposes a simple yet robust hydrogel network design that achieves ultra-high fracture resistance and self-recoverable stretchability. The network utilizes dynamic association and homogeneous crosslinking to facilitate step-by-step deformation and ensure self-strengthening without crack propagation. The resulting hydrogels exhibit comprehensive unbreakable features, including ultra-high stretchability and fracture resistance, as well as anti-crack propagation and fatigue resistance.

Summary: Artificial protein cages, such as TRAP-cages, have potential applications in vaccines and drug delivery. TRAP-cages have the ability to control the disassembly conditions by modifying the interface between their building blocks. By using TRAP rings with different numbers of monomers, it is possible to predict the formation of other cages.
