Recycling and Self-Healing of Polybenzoxazines with Dynamic Sulfide Linkages

Abstract In this work, a recycling and self-healing strategy for polybenzoxazines through both S–S bond cleavage-reformation reaction and supramolecular attractions is described. Both recyclable and self-healable polybenzoxazines can be prepared from low cost chemicals with a simple procedure in onl...
