Research Progress of Self-healing Polymer Materials

According to the classification and repair principle of self-healing polymer materials,domestic and foreign research progress on self-healing polymer materials of intrinsic structure and synthetic structure was summarized. The intrinsic structure self-healing polymer materials included rupture spontaneous growth materials based on covalent bonds such acyl hydrazone bond,disulfide bond,nitrogen oxygen bond and Dieal- Alder,reversible non-covalent bond materials based on hydrogen bond type,super hydrophobic type, ionic reaction and coordination bond ;the synthetic self-healing polymer materials involved filling microcapsule type and bionic human vascular materials. Finally,the develop trend of self-healing polymer materials was prospected.
