Adaptable materials with dynamic covalent bonds have been shown to enhance mechanical and processing properties useful for applications such as coatings, dry adhesives, and composites. Boronic ester transesterification, specifically, has a reversible exchange mechanism contributing to network stability and thermo-responsive behavior. In the present study, a synthesized boronic ester diene was incorporated into a thiol-ene network for investigation of two exchange routes. These materials were then characterized to provide insight into self-healing, thermomechanical properties, and adhesive capabilities. Details of these results as well as a comparison of adhesion derived from dry and wet preparation of the same material will be presented.
