Polymer thermosets are ubiquitous in industries and daily life owing to their thermal stability, high mechanical strength, and chemical resistance, which are mainly generated from their cross-linked structures. Meanwhile, in contrast to thermoplastics, they lack processability once cured and inevitably cause environmental issues at their end-of-life. This presentation exhibits the molecular design of functional polymer thermosets via covalent and noncovalent approaches, which not only are degradable/reusable on demand but also show programmed behavior. As an example, we could develop covalently cross-linked polymer adhesives that are reusable upon heating yet de-bondable when exposed to a specific stimulus. In addition, to achieve rapid and entirely reversible responses, we demonstrated bio-based, noncovalent cross-linking systems which allows to develop bio-based responsive vectors or smart bio-inks. |
