Bio-based vitrimers were synthesized from vanillin compounds and dynamic hardeners. Mechanical recycling of vitrimers was successfully achieved. Composites were manufactured through a rapid reprocessing stage of the vitrimers. Epoxy functionalities of the bio-based monomers affected the mechanical properties. The reprocessing stage did not influence the thermomechanical properties.

Abstract : In last years, the requirements for materials and devices have increased exponentially. Greater competitiveness; cost and weight reduction for structural materials; greater power density for electronic devices; higher design versatility; materials customizing and tailoring; lower energy consumption during the manufacturing, transport, and use; among others, are some of the most common market demands. A higher operational efficiency together with long service life claimed.

Abstract : Self-healing materials have attracted great interest in recent years. Particularly, the use of thermoset/thermoplastics blends has emerged as a good option with relatively low activation temperatures and potential infinite healing cycles. Nevertheless, a methodical study of healing conditions and evaluation is still required for further industrial development. The effect of activation temperature and crack morphology in polycaprolactone (PCL)/epoxy blends are explored.
