Summary: This study reports the direct construction of bio-based epoxy vitrimers (EVs) from renewable resources, such as soybean oil and tung oil, which exhibit multi-stimuli responsiveness and multichannel self-healing ability. The EVs showed increased tensile strength due to the formation of multiple H-bonds and increased crosslink density. The EVs with micropores or cracks achieved self-healing after heating at 200 degrees C, and a strategy for fabricating full plant oil-based EV composites using graphene was developed to achieve self-healing triggered by multiple stimuli.

Summary: Epoxy vitrimers, containing dynamic reversible covalent bonds, have advantages over traditional epoxy materials, such as recyclability, repairability, and reprocessability. The development of eco-friendly epoxy materials has been expanded by incorporating dynamic aromatic disulfide bridges. In this study, a bio-based aliphatic disulfide based on cystamine was used as a hardener with a vanillin-derived bio-sourced epoxy to prepare fully bio-based epoxy vitrimer. The presence of the aliphatic hardener significantly influenced the reactivity and dynamic properties of the epoxy vitrimer.

Summary: This paper reports the design of mechanochromic self-healing thermal management devices based on photonic vitrimer. A series of new photonic vitrimers were prepared by dynamic disulfide covalent bond and PS@SiO2 photonic crystals. The resulting photonic vitrimer exhibits bright structural colors, large tensile strain, high mechanical strength, and self-healing ability. Taking advantage of these features, a novel mechanochromic flexible wireless thermal management (MFW) device was developed, which shows promising applications in wearable electronics, vitro physiotherapy, and personal heating.

Summary: Developing amine-cured epoxy vitrimers is more significant than conventional epoxy-carboxylic acid vitrimers due to the wider usage of amines as curing agents. By synthesizing aliphatic and aromatic glycidyl esters and curing them with amine-curing agents containing disulfide bonds, dual dynamic vitrimers with integrated hydroxyl esters and disulfide bonds in the cross-linked network can be obtained. The properties of these vitrimers can be easily adjusted by changing the proportion of aromatic and aliphatic glycidyl esters, and the addition of aromatic glycidyl esters can enhance and toughen the materials without sacrificing their curing activity and reprocessing property.

Summary: In this study, multi-functional epoxy vitrimers with controllable dynamic properties, multiple-stimuli response, crack-healing, and fracture-welding were successfully prepared by introducing Fe3O4 nanoparticles. The characteristic dynamic parameters of vitrimers could be adjusted in the multi-functional epoxy vitrimers, and the material was responsive to temperature, near infrared, and magnetic field. These multi-functional epoxy vitrimers could potentially improve the reliability and extend the lifetime of polymeric materials, and the functionalization method can be applied to other vitrimer materials.

Summary: In this paper, we provide a comprehensive description of the rheological behavior of vitrimers, ranging from small deformation to large deformation. We propose concise analytical expressions to assist in data analysis and clarify emerging insights and concepts in the field. Additionally, we identify the elastic-plastic transition at a timescale comparable to the lifetime of exchangeable bonds in the vitrimer network and propose a new method to deduce material parameters. Furthermore, we investigate partial vitrimers and present a phase diagram of their strain response under different applied loads.

Summary: Thermoset elastomers possess mechanical robustness, high thermal/chemical resistance, and good dimensional stability, making them widely used in industry and frontier research. However, the presence of permanent crosslinks significantly limits their recyclability. Vitrimers, polymer networks with associative exchangeable crosslinkers, provide a solution for the circularity of thermoset elastomers. This review focuses on the design, synthesis, fundamental physics, and property evaluation of elastic vitrimers based on different types of dynamic covalent bonds. Control over the network parameters allows for tailoring of mechanical performance, network dynamics, self-healing capability, and recyclability. The responsive behavior of elastic vitrimers to external stimuli such as temperature, light, and moisture can be controlled due to the dynamic nature of reversible chemical bonds. The review also discusses the critical physical parameters of elastic vitrimers and their comparison with commonly used thermoset and thermoplastic elastomers, as well as the merits, bottlenecks, and future research directions of elastic vitrimers for practical applications in various fields.

Summary: Vitrimers with dynamic covalent bonds show self-healability and mechanical robustness, but their potential for optical function recovery is underexplored. A novel photonic vitrimer combining photonic crystals and vitrimers exhibits high mechanical stability, creep-resistance, and self-healing ability, making it suitable for sensory applications and interactive devices. This material design provides a general strategy for functionalizing vitrimers optically, showing promise for soft robotics, wearable devices, and human-machine interaction.
