Publication: Revealing the Dynamics of Sustainable Epoxy-Acrylate Networks from Recycled Plastics Blends and Oligomeric Lignin Precursors

A new study by Biorizon co-initiator VITO investigates the synergy between permanent and dynamic covalent crosslinks in a hybrid epoxy/acrylate thermoset derived from the sustainable utilization of recycled and biobased building blocks.

In recent years, the quest for carbon circularity in material fabrication has led to an increased focus on recycled and biobased resources. This study explores the development of innovative thermoset materials using recycled bisphenol A (r-BPA) obtained from end-of-life televisions and glycidylated depolymerized lignin (GDL) from hardwood. By incorporating these recycled and biobased aromatic monomers into epoxy resin systems, researchers have created dynamic crosslinked structures with tunable properties. These materials, which feature thermo-reversible β-amino esters formed through Aza-Michael addition, represent a significant advancement towards versatile, reusable, and circular materials in the field of polymer science.
