Synthesis and Characterization of Self-healing Polyurethane

Self-healing (SH) polymeric materials are able to repair physical damage and retain their originalproperties. The use of self-healing polyurethanes (SHPUs) has become very popular due to their lowcost and easy access. In this work, a series of SHPUs were synthesized using cystine dimethyl ester(CDE) disulfide chain extender with disulfide (S-S) reversible covalent bond. CDE was firstsynthesized using a simple esterification reaction and then used for synthesis of different SHPUs.The chemical structure of synthesized materials is confirmed with fourier transform infrared (FTIR)spectroscopy.
