Vitrimers are a potential commercial class of renewable plastic that uniquely blend the mechanical resilience and durability of traditional thermosets with the reprocessability typically associated with thermoplastics when subjected to high temperatures. Professor Varley, will outline the chemical structure and the mechanisms that afford Vitromers their promising properties that open up possibilities for innovations in material design, allowing for the creation of advanced composites with tailored functionalities such as self-healing, re-moldability or recyclability.
