Webb6 feb. 2024 · Importantly, this linear chain structure allows the material to be easily recycled and reprocessed by dissolving or melting, and also means the material shows potential for 3D printing or other thermoplastic remolding. Keywords: shape memory; epoxy resin; bulk polymerization; recycling; thermal-plastic 1. Introduction WebbDuring polymerization, thermosetting resins undergo a significant increase in density and a corresponding reduction in volume, commonly referred to as ‘cure shrinkage’. One effect of resin cure shrinkage is both in-plane and through-thickness reductions in part dimensions.
