Self-healing polymers are a new kind of the smart materials that have the capability of repair to themselves when they are damaged without the need for detection or artificial handling. Self-healing polymers have the potential to improve the functions of various products while extending their lifetime. Herein we designed and synthesized glyceryl methacrylate (GlyMA)-based random copolymers that can self-heal in air or water through new carbonate covalent bonding. After the preparation of linear prepolymers of P(GlyMA-r-MMA-r-BA) and crosslinked with hexyl diisocyanate (HDI) in the presence of dibutyltin dilaurate (DBTDL). For self-healing performance analyses, NMR, IR, optical microscopy, and tensile testing were carried out with crosslinked P(GlyMA-r-MMA-r-BA)/HDI acryl-polyurethane system and exploring the effects of GlyMA contents, DBTDL concentration, and various atmospheric conditions (CO2, water, N2) on self-healing behavior.
