Summary: This study evaluated radical-disulfide exchange reactions in thiol-ene-disulfide networks using different thiol and disulfide containing monomers. The results show that the stress relaxation rate in these networks can be controlled by changing the thiol-disulfide stoichiometry or the disulfide type. The combination of different thiol and disulfide monomers also influences the polymerization rate of the thiol-ene reaction.

Summary: This work reports the synthesis of polymerizable ionic liquids (PILs) and the preparation of ionogels using thiol-ene photopolymerization. The ionogels prepared with the PILs showed excellent mechanical properties, high ionic conductivity, and thermal stability. The structure of the PILs affected the polymerization kinetics and properties of the ionogels.

Summary: A family of biobased networks was synthesized from triallyl levoglucosan and multifunctional thiols via UV-initiated thiol-ene click chemistry. The thermomechanical and hydrolytic degradation properties of the networks can be tailored based on the type and stoichiometric ratio of the thiol crosslinker. The levoglucosan-based resins showed excellent suitability for extrusion-based 3D printing and demonstrated potential for sustainable rapid prototyping and mass production applications.

Summary: Polyolefins, the main components of plastic waste, lose their properties and value during conventional mechanical recycling. However, this study demonstrates the potential of functionalizing polyolefins using thiol-ene click chemistry to improve their properties. The reaction conditions can be manipulated to achieve different levels of functionalization.

Summary: With the development of electric vehicles, increasing their limited driving range has become a challenge. Lightweight design is an effective approach to address this issue. In this study, 3D printing using ene-thiol-acrylate (ETA) photosensitive resins was employed to fabricate lightweight battery compartments for electric vehicles. The results demonstrate that the printed battery compartments possess desirable mechanical and thermal properties, such as high heat deflection temperature, excellent flame retardation property, and outstanding heat dissipation performance. Additionally, the addition of a small amount of secondary mercaptan improves the resin's mechanical properties and thermal stability, solving the storage stability problem. This simple and efficient approach offers a better alternative for manufacturing lightweight electric vehicles with appropriate performance.

Summary: A new fully biobased formulation was UV cured to create a polymer network suitable for coating applications. The functional monomers used were lipoic acid and isosorbide diallyl for thiol-ene chemistry. The network's cross-linking was confirmed through ATR-FTIR analysis, and its thermal performance was characterized using DSC. Complete coating characterization was performed, showing suitable performance for coating applications.
