The synthesis of low temperature self-healable polymeric materials is challenging because their mechanical strength and self-healing capabilities have remained in conflict with each other.By introducing cellulose, composites may improve mechanical properties due to H-bonding. This research work was aimed to enhance the mechanical strength of self-healable acrylic polymers by introducing them to cellulose via graft copolymerization. For this purpose, GlyMA, BMA, and DMAEMA were grafted on cellulose by free-radical copolymerization followed by surface methacrylation. GlyMA unit in composites form metal-ligand coordinated bond with DBTDL, that imparts self-healing properties under determined CO2 and H2O conditions.The characterizations were done by using FTIR, TGA, and TEM analysis.
